Negative feedback voltage, proportional only to the value of the pulse pulse frequency and repetition frequency, from the output of the detector 3 is negative: feedback feedback is applied to the other arm of the measuring bridge. The indicator, which reacts to the unbalance of the bridge 4, is used as a measuring element of the circuit, which makes it possible to improve the measurement accuracy, since a change in the repetition frequency for a length of 1;
