Abstract
In a new circuit arrangement for improving the signal-to-noise ratio, the entire audible frequency spectrum is divided into several abutting frequency channels. Each channel supplies the respective signal part in delayed form to an amplifier with controllable amplification. The amplifier's amplification is adjusted as a function of a comparator, so that when the audio frequency signal is below a threshold value during a specified time, the amplification of the controllable amplifier is gradually decreased to the lowest amplification value. Vice versa, when the useful signal again exceeds the threshold value, the amplification is gradually controlled upward to a maximum value.
