How To Digitize an Analog Filter with the Bilinear Transform

WebFor instance, this might be used for noise reduction or separating multiplexed signals. (Chapter 3 describes how to design these analog filters). As an alternative, we could digitize the signal and use a digital filter. Say we sample the signal at 10 kHz. A comparable digital filter is carried out by the following program: WebExample: Second-Order Butterworth Lowpass In the second-order case, we have, for the analog prototype, where, from Eq. ( I.2 ), , so that (I.3) To convert this to digital form, we apply the bilinear transform (from Eq. ( I.9 )), where, as discussed in § I.3, we set to obtain a digital cut-off frequency at radians per second.
