ABSTRACT:
A pulse width modulation apparatus outputs an output pulse having an arbitrary width with respect to an arbitrary point in a pulse period. A delay means associated with a pulse cycle have multi-stage delay output means. Before a control pulse CLKP is fed to each of multi-stage delay output means, a delay time for the delay output means can be set. A rising or falling to be latched by a latch means is controlled based on delay control pulses obtained by the delay output means. An output pulse having an arbitrary pulse width with respect to an arbitrary point can be supplied without occurrence of an offset pulse or a blank duration at the start of each pulse duration.
