DEFINITION

Classification: 332/106

PULSE OR INTERRUPTED CONTINUOUS WAVE MODULATOR:

(under the class definition) Subject matter producing a final output signal consisting of a repetitious pulse wave or a pulsed continuous wave having one or more of its characteristics varied in accordance with one or more modulating signals.

(1) Note. Examples of pulse waves are square waves, sawtooth waves, and trapezoidal waves.

(2) Note. If a system includes a pulse modulator, but the final output signal is a frequency, phase or an amplitude modulated wave, the modulator is classified in subclasses 117+, 144+ or 149+, respectively.

(3) Note. Systems having a final output that is pulse code modulated (PCM) or delta modulated are found in Class 341 subclasses 126+ or 143.

(4) Note. This subclass includes pulse modulators, per se. See the SEARCH CLASS notes below for combinations with the subject matter of this subclass.
