oscillator


oscillator
i. An electronic circuit that converts energy from a direct-current source to a periodically varying electric output.
ii. The stage of a superheterodyne receiver that generates a radio-frequency signal of the correct frequency to mix with the incoming carrier signal to produce the intermediate-frequency value of the receiver.
iii. The stage of a transmitter that generates the carrier frequency or some fraction of the carrier frequency.
