|Abstract: ||This is an extension research of . In , frequency scaling of adaptive digital filter design algorithm is proposed. The pole placement technique|
is used to achieve the frequency scaling of adaptive digital filter design. In this paper, the same concept is applied for a fast way to design adaptive high-pass filters. Frequency transformation is used to transfer low-pass prototype filter into high-pass filter. State feedback is used to shift poles of the original low-pass prototype filter to the desired poles location so that a high-pass filter which has the desired passband and the desired cut-off frequency can be obtained. The responses of the frequency transformed high-pass filters and the responses of the state feedback digital
controlled high-pass filters are also compared to show the feasibility of this approach in this paper.
