PULSE WIDTH CORRECTING CIRCUIT

PURPOSE:To obtain an output having a stable pulse width by incorporating a short width pulse generator, a delay circuit, and a pulse width adding circuit which adds the output pulse of the delay circuit and the short width pulse generated from said generator. CONSTITUTION:An input pulse signal (a) or (b) is inputted to a terminal 1, and a pulse signal (c) having a pulse width t0 shorter than a pulse width t1 or t2 of the input signal is generated by a short width pulse generator 2. This short width pulse is delayed by a delay circuit 3 to output pulses (d), (e), and (f) different in delay quantity to output terminals 4, 5, and 6 of the delay circuit, and they are added by an OR circuit 7, and the result is outputted from an output terminal 8. This output pulse is a pulse signal whose pulse width T is corrected to a certain value as shown in a figure (g). The delay circuit 3 is not always provided with only three output terminals.
