Abstract

A signal generating circuit that enables to set an initial oscillation signal level to zero is provided. The circuit includes an adder 11, a first multiplier 12 with an multiplication coefficient of A1, a second multiplier 13 with an multiplication coefficient of A2, a first and second delay element 14, 15 and an initializing circuit 16. Output signal from an output terminal of the circuit is supplied to the first delay element 14, the output of it is supplied to the second delay element and the first multiplier 12. The output signal of the second delay element 15 is supplied to the second multiplier 13, the output signal of the first and second multiplier are supplied to the adder 11. The output of it is supplied to the output terminal. The initializing circuit outputs an initial value y1 and y2 of the first and second delay element such that it satisfies an equation y1*A1+y2*A2=0.
