A low-pass filter is a filter which allows the low-frequency energy to pass through. It is thus used to remove high-frequency energy from a signal. 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 ...

WebbThe Simplest Lowpass Filter Most lowpass filters smooth the input signal by taking a weighted combination of the current input sample and one or more previous samples, to calculate a weighted moving average. The simplest example of this would be a filter that outputs the average (mean) of the current input sample and the previous input sample.
