This *.gvi is a receiver (RX) which demodulates Amplitude Modulation (AM) used for Air Traffic Control in a real-time processing, with MathScript in the loop for the implementation of the squelch function. The *.gvi plots the AM signal (temporal + spectral views) and sends the demodulated signal to the loudspeakers of the host. Useful to learn AM demodulation and first integration of a MathScript in the real-time processing loop.
