Mathematical model of active quadrupole of corrective broadband amplifier with feedback

Annotation: A mathematical model of an active quadrupole corrective broadband amplifier with non-uniform frequency response (with frequency response increasing with increasing frequency) is obtained, based on a new analytical expression for the gain factor taking into account the nonlinear frequency dependence of the frequency response. Raising the frequency response occurs smoothly with increasing frequency and tends to a linear relationship at high frequencies. For the implementation of non-uniform frequency response is used serial and parallel feedback (OS). The results of computer simulation of the frequency characteristics of a corrective wideband amplifier with non-dimensional frequency response are given. A corrective wideband amplifier can be used to compensate for the unevenness of the frequency response (decrease in frequency response with increasing frequency) of the radio receiving and radio transmitting paths of radio engineering systems.
