MATLAB analog filter impulse response

Question

MATLAB's impz is used to get the impulse response of a discrete time filter. freqz is used for the frequency response of a discrete time filter. freqs is used for the frequency response of a continuous time filter. But, there is no imps - how can I plot the impulse response of a continuous time filter without this?

Answer 1

For a continuous time system the impulse function can be used to plot the impulse response. The system can be specified using zero-pole (zpk), state-space (ss) or transfer function (tf) notation.

For example:

sys = tf[1, [1 1]);
impulse(sys);
