A.V. ASADCHIY, A.I. SOLDATOV, P.V. SOROKIN, A.A. SOLDATOV
The block diagram of the monitoring device is presented. The operation principle of the monitoring device is described. The main units affecting the quality of the monitored signal reconstruction are shown. The analysis of the differentiating device and the voltage-controlled generator work is carried out. The main characteristics of the differentiating device and the voltage-controlled oscillator are given and the quality of signal reconstruction is evaluated when their parameters change. The requirements for choosing the optimal value of the derivative time constant and the frequency range of the voltage-controlled generator are specified. A calculation example of the required memory capacity for recording and reconstruction of the monitored signal is shown.
Keywords: monitoring device, differentiating device, voltage-controlled generator memory.
