Abstract
A signal generator circuit which assumes a certain prescribed value upon closure of a power supply and which is inverted upon lapse of a predetermined time after the closure of the power supply, comprising first and second flip-flops adapted to be firstly stabilized to one value upon the energization of the power supply, a logical product circuit, and memory means provided at one input of the logical product circuit, a first periodic pulse signal being applied to an inversion input terminal of the first flip-flop, an inversion output signal of the first flip-flop being written into the memory means in synchronism with a second periodic pulse signal different in phase from the first periodic pulse signal, the first periodic pulse signal being applied to the other input of the logical product circuit, an output of the logical product circuit being applied to an inversion input terminal of the second flip-flop, an inversion output signal of the second flip-flop being used as an output signal of the signal generator circuit.
