Abstract

The invention relates to a peak detector of analog signals intended for magnetic tape memory of automatic computers. The object of the invention is to create a simple peak detector that is reliable. This object is solved by means of a peak detector that is composed of "n" channels, each of which contains a preamplifier, the output of which is connected to the information input of a two-way limiter, the two comparison inputs of which are connected to the upper threshold line and the lower threshold line of the limitation. The output of the limiter is connected to the input of a differential amplifier, the output of which is connected to the input of the zero detector and its output is the output of the channel. The advantage of the invention lies in the simplified connection and a significant reduction in the number of circuit elements.
