Abstract
PURPOSE: To simplify constitution and enhance economy by phase-inverting the output signal of a first adder and supplying the same to a delay circuit and a feed forward circuit and obtaining the reverberating output signal from a second adder.
CONSTITUTION: A resistance adder A10 consists of fixed resistances R10, R20 having a mutually equal resistance value (r), and a phase inversion circuit I which has a phase inversion type buffer amplifier IB of gain-1 inverts the phase of the added output signal obtainable at the point of connection of the resistors R10, R20 of the circuit A10. Variable resistance attenuators VR10, VR20 which have a mutually equal resistance value R being varied cooperatively constitute a feedback circuit B0 and a feed forward circuit F0 respectively. An analog delay element, etc. are used for a delay circuit D0. Hence, the output signal of the circuit A10 is phase- inverted in the circuit I, after which it is applied to the circuits F0, D0 and buffer amplifying effect is obtainable in the circuit I, whereby the constitution is simplified, cost reduced and economy enhanced
