DEFINITION

Classification: 327/116

Frequency multiplication:

(under subclass 114) wherein the repetition rate of the output pulses is greater than the frequency of the input signal.

(1) Note. Miscellaneous frequency mixing which produces sum or difference frequencies of two input frequencies is

classified in subclass 113. Rectangular or pulse waveform frequency mixing is classified in subclass 114.
