Modulated
From GUI we can generate random binary data, modulate them in frequency, add noise to the modulated signal and final demodulate received signal. Also it's possible to view some performance of the system.

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...
