[Herp] just shared a nice 1MHz Arbitrary Waveform Generator (right ... output is available to use a PIC32 PWM signal. The platform can read WAV audio files stored on microSD cards and also ...

Carrier Wave Generator The Wave Generator creates a high-frequency radio signal. The frequency of this signal is many times greater than the frequency of the audio wave. This signal will "carry ...

Pulse counting works by generating a narrow, fixed-width square wave pulse at a set point ... we can tease out the original audio frequency signal. Simple in theory is often more complicated ...

The difference is in how the carrier wave is modulated ... slight changes in amplitude don't matter -- since the audio signal is conveyed through changes in frequency, the FM receiver can just ...
