Abstract

PURPOSE: To make it possible to set freely the crossover frequency of a fixed band- pass frequency signal extracted by a delay method and arithmetic method, by varying the frequency of a clock signal.
CONSTITUTION: A sound signal inputted from terminal 1 is supplied to delay-line filter 2 and delay circuit 3, whose outputs are both supplied to coefficient arithmetic circuit 5 with coefficients K1 and K2. On the other hand, clock-signal oscillator 15 is provided and then the oscillation frequency of oscillator 15 is varied, so that filter 2 and circuit 3 will vary in delay time uniformly. Consequently, only the crossover frequency can be varied while maintianing the pattern of frequency characteristics as shown in the figure.
