DEFINITION

Classification: 331/50

(under subclass 46) Subject matter wherein two or more oscillators are effectively connected in concatenation, that is, the output circuit of one oscillator is connected to the input circuit of a second oscillator so that the first oscillator drives the second oscillator. The second oscillator may drive a third oscillator, the third oscillator a fourth oscillator, etc.

SEE OR SEARCH THIS CLASS, SUBCLASS:

38+, for beat frequency oscillator systems wherein plural beating stages are cascaded.

45+, for polyphase output oscillators which may utilize cascaded oscillators.

55, for plural oscillators wherein a periodic source, recited broadly, synchronizes, triggers or pulses at least one of the plural oscillators.
