DEFINITION

Classification: 327/131

Generating sawtooth or triangular output:

(under subclass 100) Subject matter wherein a waveform is generated having a positive slope followed immediately by a negative slope.

(1) Note. The positive slope is generally gradual (e.g., by slowly charging a capacitor, etc.), and the negative slope is generally much more rapid (e.g., by quickly discharging a capacitor).

(2) Note. The slopes of a sawtooth waveform produced may only approximate a straight line.
