Listening FM by Aliasing

Since the sample rate is 64 MS/s, A station at 88.5 aliases to 24.5MHz.    A station at 103.5 would alias to the same place, so you won't be able to separate them if both are transmitting.

By the way, the ADC can actually sample signals as high as 500 MHz with only a few dB of loss, and signals as high as 1300 MHz with about 20 dB of loss.


  1. so any way of filtering them? (using speech processing?? thinkk.. think...)
