Abstract

The invention discloses an instant messaging system comprising a signal frequency collection circuit, a comparison compensation circuit and a filtering and voltage stabilization output circuit, wherein the signal frequency collection circuit collects signal frequency in a signal transmission channel in the instant messaging system, the comparison compensation circuit compares and adjusts the signal frequency, the signal frequency is proportionally amplified by an operational amplifier AR3 and then input into the filtering and voltage stabilization output circuit, meanwhile a compensator AR4 isdesigned for compensating the level of the operational amplifier AR3, the filtering and voltage stabilization output circuit outputs a signal after performing filtering and voltage stabilization on the signal, that is to say, the signal flows into the signal transmission channel of the instant messaging system. According to the system provided by the invention, the problem that the signal is instable and the signal transmission efficiency of the instant messaging system due to the fact that the signal frequency in the signal transmission channel in the instant messaging system has a time-varying characteristic and the frequency conversion is relatively fast is effectively solved.

Description

technical field [0001] The invention belongs to the technical field of instant messaging and relates to an instant messaging system. Background technique [0002] The rapid development of communication technology in today's society has provided great convenience to people's lives, and at the same time profoundly changed people's lifestyles. Instant messaging systems provide people with convenient multimedia communication services such as voice and video, and can communicate anytime, anywhere. Since the frequency of the signal in the signal transmission channel in the instant messaging system is time-varying, and the frequency conversion of the signal transmission channel in the instant messaging system is relatively fast, the signal is extremely unstable, which will reduce the signal transmission efficiency of the instant messaging system. Contents of the invention [0003] The purpose of the present invention is to provide an instant messaging system, which solves the pro...
