Abstract

본 발명은 자동응답 시스템에 있어서 자동이득 조절회로에 관한 것으로 특히 가입자가 자동응답 서비스를 받을시 가입자선호 길이에 관계없이 일정한 레벨의 음성신호를 들을 수 있도록 이득을 조절하는 회로에 관한 것이다.The present invention relates to an automatic gain control circuit in an automatic answering system, and more particularly to a circuit for adjusting a gain so that a subscriber can hear a certain level of voice signal regardless of the subscriber's preference length when receiving an automatic answering service.

자동응답 시스템에 있어서 서비스음성신호를 기준신호 비교하여 선호 길이에 관계없이 가입자에게 항상 일정한 레벨의 음성신호를 들려줄 수 있는 질 높은 서비스를 제공할 수 있다.In the automatic answering system, a service voice signal may be compared with a reference signal to provide a high quality service capable of always providing a constant level of voice signal to a subscriber regardless of a preferred length.

Description

Automatic Gain Control Circuit

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명에 따른 자동이득 조절회로도.1 is an automatic gain control circuit in accordance with the present invention.

Claims

An automatic gain control circuit of an automatic answering system, comprising: comparing means for outputting a gain adjustment control signal by comparing a subscriber service voice signal with a reference signal, and gain adjustment for adjusting gain by a gain adjustment control signal output from the comparison means; And means for transmitting / receiving and separating means for transmitting / receiving and outputting the gain-controlled signal input from the gain adjusting means and the signal input from the subscriber side, respectively.

The circuit of claim 1, wherein the transmission and reception separation means performs a hybrid function and a balancing function.

In the automatic gain control circuit of the automatic answering system, a hard disk 10 for storing a voice signal, a hard disk driver 9 for accessing a voice signal from the hard disk 10, and a voice signal received from a subscriber And a transformer (1) for impedance matching and transmitting the response service voice signal read from the hard disk (10), and separating means connected to the secondary side of the transformer (1) to provide a hybrid function and a balancing function; A codec 8 for inputting and demodulating and outputting a voice signal of the subscriber side output from the transmission and reception separation means and a service voice signal from the hard disk driver 9, and a service voice signal modulated by the codec 8; Comparison means for outputting a gain adjustment control signal by comparing with a reference signal, and adjusting the gain by the gain adjustment control signal output from the comparison means. And a gain adjusting means for outputting to the transmitting and receiving separating means.
