.~ Cyclic frequency sweeping means (e.g., vibrato)
DEFINITION
Classification: 331/178
(under subclass 177) Oscillators wherein means is provided for periodically or continuously varying the output frequency of the oscillator over a range of frequencies. The means, for example, may be (1) another oscillator driving a reactance tube in the frequency determining circuit of the oscillator whose frequency is being swept, or (2) a continuously running motor driving a reactance element in the frequency determining circuit of the oscillator whose
frequency is being swept.

40, for beat frequency oscillator systems with frequency sweeping means.
106, for oscillator whose output amplitude varies periodically or repetitiously and which include frequency sweeping.
