WebbSignal filtering, Signal suppression, Signal processing. In the field of signal processing, a filter is a device that suppresses unwanted components or features from a signal. The most commonly used filters are low-pass, high-pass, band-pass and band-stop. Characteristics that describe filter are its type, cutoff frequency, order (steepness). Webb1. A highpass filter is to be designed, using the ‘direct’ method, i.e. by placing transfer function poles and zeros at suitable points in the z -plane. The filter is to have a transfer function of the form T ( z) = k ( z − 1)/ ( z − a ), a cut-off frequency which is 0.125 of the sampling frequency (0.25 fN ), and a gain of 1 at the ...
