ABSTRACT:
A transmission arrangement provided with at least one adjustable network whose transfer characteristic between input and output as a function of the frequency .omega. within a prescribed frequency band is approximately equal to C exp [kf(.omega.)], where C is a constant and k a continuously variable parameter.
A simple design as well as a large practically feasible adjustment range are obtained because the adjustable network comprises a plurality of channels between input and output and the transfer characteristic of a channel is approximately proportional to a term, different for each channel, from the series of terms of the development of exp [kf(.omega.)] to powers of kf(.omega.), the number of terms corresponding with the number of channels.
