"WebA typical method to transform a continuous-time IIR filter into a discrete-time IIR filter is the impulse invariance. In this method, the impulse response of the discrete-time IIR filter is obtained by sampling the impulse response of the corresponding continuous-time IIR filter, i.e., h(n)=Th c (nT).

WebAs discretization example we are going to use the transfer function of a first order system (also known as a low-pass filter): \[H(s) = \frac{1}{T_{c} \cdot s + 1} \tag{1}\] where T c [s] is the time constant of the system. We can implement the first order system transfer function in an Xcos block diagram and plot its response to a step input.
