GNU Radio - Examples

350 Hz sine wave out sound card speaker ( mono_audio_out.cc)
FFT display of high speed ADC input ( adc3_fft.cc)
Single channel FM demodulation. Input is sucked from the IF of a really cheap AM/FM radio kit and piped into high speed A/D, then into this program ( elenco_fm_demo_no_gui.cc)
Dual channel FM demodulation. RF input is from cable modem tuner module. Tuner module IF output is 5.75 MHz. We connect that directly into the 20 million sample/sec A/D, and then from that signal, extract and demodulate 2 stations ( fm_demod2.cc)
