Phase controlled oscillator circuit with input signal coupler

An oscillator circuit comprising:

• oscillator means having a resonant frequency;
• an input signal having a frequency about equal to or less than the resonant frequency and having a phase;

• coupler means which couples the input signal with an oscillating signal in the oscillating means to filter pulse width variations of the input signal.

An oscillator circuit comprising:
