Yes, for low speed "FSK audio tones" and with a fast enough micro.
Teridian (formerly TDK semicoductors) used high speed 80c51's to decode / encode modem tones to 2400 baud. What the FSK frequencies? Is it RF FSK ? Is it 2 level FSK or multi level FSK? What's the lowest level detection in VdBm you need to detect? What's the highest? What's the data rate/speed/baud rate? Joe |
