Phase-lock loop circuit with fuzzy control |
摘要 |
A phase-lock loop circuit (1) with fuzzy control, which comprises a phase comparator (2) whose output is connected to a low-pass filter (3) that is suitable to drive a voltage-controlled oscillator (4); the phase comparator (2) is suitable to generate a signal (z) that represents the phase difference between an input signal (x) and a signal (y) generated by the oscillator. The particularity of the invention resides in the fact that the oscillator (4) is furthermore driven by a control signal (Vinj) generated by fuzzy control means (5) the input whereof is the signal (z) representing the phase difference. <MATH> |
