DEFINITION

Classification: 327/237

Variable or adjustable:

(under subclass 231) Subject matter wherein the phase control is (a) continuously changed or (b) modifiable (either automatically or in response to an operator) to various fixed delays.

SEE OR SEARCH THIS CLASS, SUBCLASS:

270, for output waveform production delay via variable or adjustable multiple outputs to effect a plurality of delay intervals.

276, for output waveform production delay where a single output has variable or selectable delay.
