Analog jobs

I need a arduino base unit to collect analog inputs and send them via a wiznet ethernet chipset.

I want to create a pair of circuit boards which work in tandem to transport some analog data over standard CAT5 cables in a digital format. I am looking for someone to do electronic design, component selection, schematic capture, PCB layout, testing and debug of a prototype, and a final "turn"on the PCB design. Altium is preferred, but I can accept other formats. The incoming data is 6 differential analog signals, one digital signal, and an RS-232 signal. The only signal returned to the source is RS-232. The analog signal should preferably have a 96kHz sample rate. The output should mirror the input: i.e. 6 differential Analog signals, one digital signal, and the RS-232 data. I have identified an ADC and DAC with parallel I/O which I think would...

...exploded in popularity during the 1990s, due to the 1987 repeal of the Fairness Doctrine, which meant that stations no longer had to "balance" their day by programming alternative points of view. The FCC has recently approved a transition to digital radio technology which allows both FM and AM stations to"piggyback" digital data on top of their existing analog broadcast. When the transition is complete at some point in the far future, the analog broadcast. will be replaced with true high-quality digital broadcasts. See IBOC and HD Radio. A new form of radio that is gaining popularity is satellite radio. The two biggest subscriptions based radio services are Sirius Satellite Radio and XM Satellite Radio, which have recently both merged together to...

The intension of the project is to communicate the industrial data (temperature sensor, level sensor, flow meter etc) between plant and embedded processor. This also have the global communication capability using GSM data communication with mobile handset device. Also online (pc interfacing) and offline (micro sd card interfacing) data logging can be done. The industrial plant have many type of analog data like temperature sensor , level sensor ,flow meter , pressure sensors etc. So in plant this type of data should be analysed and then processed to achieve some specific action regarding it. The data can be processed with the embedded processor. The embedded processor must be programmed such that the data can process and give the require output.

I need a Basic breakout board for this product TVP7002 ((NRND) Triple 8/10-bit, 165/110MSPS Video ADC) it needs to be a 4 layer PCB, with connections for 1.9V and 3.3V VCC with separate digital/analog GND. As well, it needs to include a VGA port ( Mouser Part #: 636-193-015-213R531), headers for the RGB data out and SDA/SCL pins. Since this is for a potential video application, adherence (or as best as possible) to the MFG guidelines. Ideally I would prefer just the basic PCB schematic. Also (if possible), since this will be an ongoing project of mine I would prefer if it were designed using this web site I have included the Datasheets for both the TVP7002 and VGA, as well as some misc relevant info.

TI PCM4222 is a high quality ADC, with many options (for complete documentation and partlist see attachments). The aim is to have a simplyfied circuit with only the following capabilities: - Audio In1 and Audio In2 - I2S out - SPDIF out - power supply connection (PS will be provided separately) - ADC control options: I2S and sampling frequency Please note: Based on the required input-output specs additional control options might be useful which we did not think of. If You think that additional control options of the ADC might be a plus, please contact us, we might enhance the project! Task 1: - simplify the drawings of the PCM4222 evaluation board according to required capabilities (just crossing out parts/highlighting necessary sections on the drawing is perfectly enough!) ...

Remote control airplanes get lost in fields with tall grass. The RC Plane will be equipped with a class 1 (high power) bluetooth device. The android phone will try to pair to it but will not be able to until it gets very close by because it is class 2 (lower power) So I want a digital (raw decimal) and analog (bar graph) display of RSSI on the upper portion of the cellphone screen. This will help someone 'hone in' on the high power device. This will help the cell phone user get close enough to the device to actually pair to it. Once paired it must mount as a COMPORT so RSSI a few other parameters can be displayed on the remainder of the screen in a 'blueterm' like window. I found a small posting that claims RSSI is available during pairing here:

I would also like to judiciously extend the original with AudioBus and IAA support, presets, and perhaps some functional extensions (The Digitech JamMan is, to a large degree, an outgrowth of the 42. I can tell you stories) The skills needed are iOS app development, DSP analog audio circuit emulation, a knowledge of MDI, and a background in audio/music apps enough that you know what it is and you can appreciate what's important. What I propose is to pay nominally, and split the net profits 50/50. I think that's fair. I'm realistic about the earning potential and I want to do this just to do it. I have listed it as a Small Project, but I ...

Detail described in the attachments - but here is a summary. I have a test device that includes a 4A 24V DC motor that drives a small pump. The pump can only operate for short periods, but I need to leave the device unattended for a few days at a time. The role of the PLC is to control when the pump starts based upon digital and analog inputs, and limit the time that the motor operates to a few minutes. It will also have the option to switch it off if a temperature sensor detects that it is getting too hot, or a pressure sensor indicates a line blockage. Electrical Drawing I need to have a proper electrical schematic drawn up showing all the switches, wires, and connections via terminal blocks where they are required. This has to be suitable to give to an electrician to wir...

This project is based on homework that is due in about 12 hours. Designing analog amplifier using basic undergraduate level equations. I can do the pspice programming once the amplifier is designed, I am at loss as to how to design it however. If you can take this project I will pay you handsomely, should be only about 2-3 hours of work and I can pay up to $200 depending on the quality of the work provided and whether it matches the standards given (I can test it in pspice). If you are interested then message it to me.

In the last few weeks I read every detail of similar projects and collected all the appropriate information and made a list of recommended components, but I will need help with finalising the development steps and the final BOM. I found ready-made solutions for high-resolution scales, with recommended Analog to Digital Converters, CPUs and Development Kits. In addition there are circuit diagrams and C source codes available on the Internet for free, too. I need you to supply the proper flow charts, circuit diagrams, and C source codes of the project. (Free Internet stuff can be used for these.) I need a working prototype (I can build it with online supervising) on a solderless brea...

...anything that goes & is changeable afterwards) to flash on an embedded system (which I haven't purchased/designed yet). I know a lot of the basics but I'm still a student in electrical engineering. The system gets 1 analog input to turn the system on or off (it's 12 V) and 1 analog input (varying between 2 - 5 V). When the system's on it has to output 5 different signals continuously: 4 analog signals and 1 digital signal with a constant duty cycle (it may have an amplitude of 5 V, but 12-13 V would be better). 3 out of the 4 analog signals vary between 0 - 5 V. The other analog signal is a bit more complex, it has to be the signal of a crankshaft VR sensor (with 60 -2 teeth). It has an amplitude varying between -5 and 5 V...

The project is all about retrieving the audio siganl and processing it in matlab ,the further details are below. i want the matlab code as soon as data file in matlab is added. As a communication engineer, you are asked to recover some messages from a sampled received signal (). Frequency division multiplexing (FDM) with some form of analog modulation (AM, FM) was used to produce this signal. It has also been contaminated by additive white channel noise. Some prior knowledge: • Sampling rate fs=220,500 sample/second • There are one or more than one messages • The messages have zero DC level • The bandwidth of each message signal is less than 10,000Hz • Each carrier frequency is a multiple of 10,000Hz • A different type of modulation may be used...
