Abstract
The amplifier circuit produces a feedback signal. It determines if the amplitude of the feedback signal is greater or less than the amplitude of the input signal. A control signal is produced which is a functin of this amplitude determination. The circuit has two continuous voltage sources. The voltage of the second source being less than that of the first. The circuit produces an output in series with a delayed response circuit. It disconnects the second source from the delayed response circuit and simultaneously connects the first source to the delay circuit, when the polarity of the control signal is negative. The connection is maintained during the period of negative polarity. The first source is disconnected and the second source connected to the delay circuit when the polarity of the control signal is positive. The connection being maintained during the period of positive polarity. The amplifier permanently measures in the form of the reaction signal, a parameter which represents the instantaneous state of the output.
