Sampling Frequency Offset
In wireless topology we using filters as main part of system, we proposed a flexible filter for multi-purposes working at ISM band frequency. Obviously the filter idea works by splitting the Band Pass Filter into two types H.P.F & L.P.F controlled by logic circuit to select the desired filter....

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...
