AFSK transcever for Silicon labs Si446x
$30-250 USD
Paid on delivery
An AFSK signal is an FSK signal whose DR changes with the two audio tones’ frequency. As an example take the Bell 202 modulation format where one audio frequency is 1200 Hz while the other is 2200 Hz. From the receiver’s perspective these signals translate to 2400 bps and 4400 bps DR streams, respectively. The reason the DR is twice as much as the audio tone frequency is that a full cycle on the audio tone translates to two bits: a 1 and 0 (or vice versa).Observe the received digital signal by placing RX_DATA to one of the GPIOs where the audio tones will appear as square waves as opposed to sine waves. Run an algorithm on your host MCU that decodes the data stream.

hi, I have past experience with sil labs rf devices ,I can work on this project professionally
I have a Master degree in Electronics and my thesis work was the design and implementation of a QPSK modulator/demodulator in a Xilinx FPGA so I strongly believe I am a perfect fit for the project.
