fsk demodulator circuit using lm565

Posted on Feb 4, 2014

This is a design circuit for the FSK demodulator, that is the electronics device that converts the FSK signal to serial digital signal. To transmit digital serial data we use FSK modulation and to get back the digital data at the receiver, we need to demodulate it. This is the figure of the circuit; The main component of this circuit is LM565. For
