Phase-lock loop circuit with fuzzy control

A phase-lock loop circuit with fuzzy control, includes a phase comparator whose output is connected to a low-pass filter that drives a voltage-controlled oscillator. The phase comparator generates a signal that represents the phase difference between an input signal and a signal generated by the osc...

Beschreibung
Zusammenfassung:	A phase-lock loop circuit with fuzzy control, includes a phase comparator whose output is connected to a low-pass filter that drives a voltage-controlled oscillator. The phase comparator generates a signal that represents the phase difference between an input signal and a signal generated by the oscillator. The oscillator of the present invention is furthermore driven by a control signal generated by fuzzy control. The input of the fuzzy control is the signal that represents the phase difference.
