ABSTRACT:
A method for removing a noise of a communication system, and more particularly, a method for removing switching noise generated during connecting and disconnecting a channel is provided. A method for removing switching noise during the start of communications includes the steps of calling a desired receiver by dialing the number of the desired receiver at a transmitter, connecting a channel of the receiver when the desired receiver responds to the call, muting a speaker of the receiver for a predetermined time after connecting the channel between the desired receiver and the transmitter, and connecting a channel of the transmitter after lapse of the predetermined time. Accordingly, the influence of the switching noise of the communication start and end is reduced by muting the respective transmitting and receiving terminals for the time interval generated during connecting and disconnecting the channel between the terminals.
