I want to know how to find the parameters of IIR and FIR filter
float32_t * pState
float32_t * pkCoeffs
float32_t * pvCoeffs
Actually i have to implement digital IIR filter on the control
side(bessel filter with cutoff frequency 15Hz ).
please help me to find these parameters
Take reference from DSP LIB based examples from Pack Installer.
Click on ARM in Device section and you should see these examples
under Examples tab
Well, the first hit googling "cmsis dsp software library
"This user manual describes the CMSIS DSP software library ...
Which would seem like an ideal place to start ...
But I think the OP might actually want a primer course in digital
filters and computing filter constants.
