ABSTRACT:
A pulse width modulation circuit apparatus of a digital type using a delay circuit and a decoder, which is provided with a delay control circuit for driving the reset-set type flip-flop of a last output stage and which provides the flip-flop with a mode determination function, whereby the range of the operation frequency is broadened, the generation of a blank pulse and offset pulse can be suppressed, and a higher precision gradation expression can be realized.
