Abstract

PURPOSE:To perform correct waste time compensation even in a transient state in which the waste time is fluctuating by making use of the fact that the output of an output terminal is obtained from the same output despite the fluctuation in the waste time in the case of performing the compensation of the waste time by the signal from the waste time terminal. CONSTITUTION:Clock of a fixed period is supplied to a timer 31 from a reference time generating circuit 32, and is outputted from the timer 31 after it is controlled to the clock of a fixed period corresponding to the waste time signal from its terminal 24. The readout period for a memory 26 is determined by this clock. Hence if the control signal inputted to the terminal 21 is defined as IN(t), the signal readout from the memory 26 is delayed by the waste time (n) to IN(t-n), hence the output OUT(t) thereof is expressed by the equation I. The (n) in changed by the signal from the terminal 24, whereby the waste time compensation is accomplished. In this case, the output of the terminal 25 is obtained at all times from the same terminal irrespective of the fluctuations in the waste time; therefore, even in the transient state in which said time is changing, the correct waste time compensation is performed.
