ABSTRACT:
A broadband signal switching equipment constructed in field effect transistor technology has gates at the inputs of the switching point matrix, and output drive circuits having threshold values at the outputs of the switching point matrix. The output signal of a connection, which preferably proceeds via a switching point residing in the center of the switching point matrix and which transmits a fixed signal during each bit through connect interval, is used to block the gates on the input side, given a change of the signal condition of the output signal, whereby a further charge reversal of the switching point matrix output lines is avoided.
