MULTIPARAMETRIC MODEL OF FREQUENCY TRACTION DEVICE AND INTERFACE OF THE PRORAM FOR ITS ANALYSIS
The article is devoted to the problem of designing frequency tracking devices in a complex signal and noise situation. The article presents a mathematical model of the device, which takes into account possible structural and parametric changes of the device, changes in the frequency of the input signal, its angular modulation and time-varying noise level in the input mixture. Developed and described software application for the analysis of this model allows you to quickly change the values of parameters and monitor the response of the device to changes in the input signal.
