Modulation
The Chorus effect was originally designed to simulate several voices: just as if several persons were playing together the same notes but with a variable delay between them. This is the effect you get with Blue Cat's Chorus when setting the rate parameter to a small value. But this plug-in also...

This script simulates the Binary Amplitude Shift keying. Since BASK is a digital modulation scheme, you can modulate as many bits as you want. however, I have only simulated it for 5 bits, so that the results are visible.This is code for BASK only, means it can only modulated two digital states.I...
