A high-pass filter relates to wireless devices for signal filtering and may be used in automatics and telemechanics for control system correction. A method based on description response of filter with fractional rational transfer function:,Where- fractional rational transfer function,- operator;-filter order,- low cutoff frequency.The distinction of the invention from the known one consist in that a filter output signal is formed using procedure of operational transposition with help of n operation modules that use operation of comparison of input signal and summation result, multiplication of result of comparison and a compensation factor, summation of the product and a signal delay. The proposed method allows performing filter synthesis for given value of low boundary of filter frequency range and performing correction thereof using a compensation signal that simplifies implementation of the method and extends functional capabilities. |
