(under subclass 1) Subject matter wherein the A.F.S. loop circuit of the oscillator is provided with means to limit the amplitude, or to maintain the amplitude constant, or to correct or otherwise compensate for undesired changes in amplitude of a control signal in the loop circuit, or to disable the A.F.S. loop if the amplitude of the control signal (e.g., reference oscillator signal) is below a predetermined level (e.g., the level wherein noise signals may adversely affect the oscillator A.F.S. and thereby cause the generated frequency to be shifted outside its proper range).
