I am writing to know if is possible to modulate with ASK a signal using java. Does anyone know anything about that?
If you just want to amplitude modulate a carrier signal within the audible spectrum then you can just change the amplitude of a synthesised sine wave on-the-fly.
So the carrier signal would be:
where
A= amplitude,f0is the carrier frequency (Hz), e.g. 10 kHz,Fsis the sample rate (Hz), e.g. 44.1 kHz, and n is the sample number.You would change A according to your modulation scheme, e.g. at the start of every symbol period (e.g. every 10 ms, for a symbol rate of 100 baud) set A to the required value.
