ABSTRACT:
A method and apparatus for controlling the gain of receivers in a computer-to-computer communications network using intelligence in the signal to control the receiver gain. Each of the computers in the communications network has associated therewith a transmitter and a receiver for transmitting and receiving data from one or more of the other computers in the system. Preferably, each such receiver has associated therewith an automatic gain control circuit which operates automatically to increase the gain when low level signals are received and to decrease the gain when high level signals are received. At least one of the receivers and preferably each receiver in the system has associated therewith a memory device for storing compiled data indicative of the anticipated signal level from every other transmitter in the system. Means are provided for setting the level of gain in the receiver that is expected to receive a signal to the level expected to be required for proper reception of a signal transmitted by the transmitter next expected to send in accordance with the information stored in the memory device.
