い１、入力端Ａである時刻における入力ｋＱ。DESCRIPTION OF EMBODIMENTS FIG. 1 is a block diagram of an electronic echo device according to an embodiment of the present invention. An m-stage delay circuit 1 is configured with an inductance L and a gear pantance C from the input terminal A, and an inductance L' and a capacitance C are connected to the next stage of the delay circuit 10 via an attenuator 3.
A delay circuit 2 consisting of n stages is connected, an output resistor 6 is connected in parallel to the next stage of the delay circuit 2, and a second attenuator 5 is further connected. The output of the attenuator 5 is fed back to the input stage of the delay circuit 2. 1. Input kQ at input terminal A at time.

ような出力関係になり、漸次、出力は減衰していく。The attenuation rates of attenuators 3 and 6 are 1/α and 1/β, respectively, and the delay times of delay circuits 1 and 2 are τ1. If τ2 is set, the output relationship will be as shown in FIG. 2, and the output will gradually attenuate.

たず特性の良い遅延回路を構成する。The second attenuator is a transistor attenuator whose input and output are connected by a coupling capacitor C for impedance matching. That is, in a circuit that loops through the delay circuit 2 at the subsequent stage using the output resistance of the attenuator 3 and the resistor 6, the input/output impedance of the transistor attenuator 5 is 2J.
By setting τ5 resistance, it serves to prevent reflected waves on the input and output side.Since the delay circuits 1 and 2 are composed of inductance and reactance, they do not have frequency characteristics,
The delay time is the same for any frequency, and the input resistance value R of the attenuator 3 connected to the first delay circuit 1 is −1−.
Since the circuit is B-near positive, the signal from the input terminal A to the output terminal B-4 and the signal looped through the switched second delay circuit do not have any distortion, forming a delay circuit with good characteristics.
