impulse calculates the unit impulse response of a dynamic system model. For continuous-time dynamic systems, the impulse response is the response to a Dirac input δ(t).

“IIR” means “Infinite Impulse Response.” 1.2 Why is the impulse response “infinite?” The impulse response is “infinite” because there is feedback in the filter; if you put in an impulse (a single “1” sample followed by many “0” samples), an infinite number of non-zero values will come out (theoretically.)

When decimating by a factor of M, the signal should be prefiltered by a lowpass filter with a normalized cutoff frequency of 1/M in order to prevent aliasing distortion. The user of the function is responsible for providing the filter coefficients. The FIR decimator functions provided in the CMSIS DSP Library combine the FIR filter and the decimator in an efficient manner.

A FIR filter impulse response h[n] is used for the development. FIR filters are preferred because they can be designed to preserve the phase and consequently would not cause distortion. The linear-phase FIR filter requires the impulse response to be symmetric or anti-symmetric around its …

Impulse Response. Before we can get started with plotting the frequency response of the averaging filter, we must determine the impulse response of this filter. The impulse response, as implied by its name, is the filter’s response to an impulse input. Let’s define what an impulse is: an impulse is a single point with an amplitude of 1.
