Abstract :
Wideband highpass filters are widely used in applications such as wireless codec design or ECG signal processing. It is well-known that wideband digital filters suffer from large sensitivity and roundoff noise. In this letter, an efficient pipelined WDF (Wave Digital Filter) design method for wideband filters is proposed. Using one design example, it is shown that the hardware cost can be reduced by 45% by using the proposed approach instead of conventional approaches
