The working principle of the call between the master and slave computers of a cordless telephone
The composition and characteristics of a cordless telephone circuit, amplifying circuit and low host duplex filter test call cry control circuit Xiang side circuit control high frequency signal and antenna circuit a main machine electric rice circuit are connected electrically, Lu adjustment side signal generating circuit duplex filter selecting host transmitting circuit received from the machine launch the high frequency signal, then send to the antenna and the high frequency receiving circuit, clutter suppression, and the high frequency signal receiving strict isolation, with lightning, high pressure, this part of the circuit consists mostly of cascaded multilevel filter
A cordless telephone is also called a master slave machine. It consists of two parts, the host computer and the slave computer. The host computer is connected with the local telephone network, and the host computer and the slave computer are connected by radio mode, so that the sub machine can dial or receive the user in any 1 of the calling network at any time in the effective range.
By sending radio waves over long distances, they complete the work of voice transmission that was originally performed by telephone lines, because radio encounters obstacles can be reflected or absorbed, so there is a certain range of use
