Binary Frequency Shift Keying

This script simulates the Binary Frequency Shift keying. Since BFSK is a digital modulation scheme, you can modulate as many bits as you want. however, I have only simulated it for few bits, so that the results are visible.

This is code for BFSK only, means it can only modulated two digital states on two frequencies.

I hope this will help out students and instructors alike.
