Analysis of the application of serial connection of the same type bandpass filters in the sensor signal processing channel in the information control system

Abstract

The paper is considered the problem of constructing system components with the possibility of rearranging their characteristics depending on the operating conditions. A new approach is proposed for calculating the parameters of a new connection with a series connection of low- order components of the same type. The resulting ratio allows you to accurately calculate the frequencies of the n-th connection of the same type components. In addition, such a connection allows increasing the rate of rise and falling of the fronts of the amplitude frequency characteristic and reducing the bandwidth by 3 times with eight connected filters of the same type. Bandpass filters and notch filters are considered. Behavior of the AFC for serial connection is described.
