Hi,
I am doing a project that requires me to generate fsk signals to do some testing and demodulation on it for research purposes.
The idea is simple. Using 3 simulate signals consisting of 1 square wave modulating signal, and 2 sine wave upper and lower shift frequency signals. I connect the upper and lower shift frequencies to the T/F pins of a selector device, the selection pin I connected to the square waveform output.
How do I convert the dynamic value of the output signals into boolean T/F so that the selector pin can accept the input?
