.~> Triggering or pulsing (e.g., burst generators) {1}
DEFINITION
Classification: 331/172
(under the class definition) Oscillators wherein (1) means are provided for maintaining a predetermined phase or frequency relationship between two sources of waves, one source being an excitation or standard source (snyc source) and the other source being the controlled oscillator, or (2) means are provided to initiate or stop oscillation of the
oscillator.
