The FSK signal demodulation circuit composed of the digital phase-lock


Posted on Feb 6, 2014

In Figure 7-2 is the FSK signal demodulation circuit composed of the digital phase-lock. The circuit consists of 2 oscillators with different frequencies, i.e crystal oscillators X (the frequency is 983.04KHz) and X2 (the frequency is 1.2288MHz) compose the oscillator, and X2 consists of the frequency converting circuit 74HC157, frequency splitting circuit..
