Circuit Description

This circuit implements a simple FSK modulator (frequency shift keying). Depending on the state of the select input signal, the state machine output toggles every second or every forth clock cycle, that is, the frequency of the output signal is modulated by the input signal.

The following screenshot shows an example of the FSK modulator waveforms:
