Class Information
Number: 331/182
Name: Oscillators > Amplitude control or stabilization
Description: Subject matter wherein means are provided in the oscillator circuit for adjusting, controlling or regulating the amplitude of the generated oscillations and not provided for in any preceding subclass. The oscillation amplitude control means may be manually set or varied or may be controlled automatically responsive to changes in some condition, such as the amplitude of the generated oscillations.
