Hi
I want to know how to find the parameters of IIR and FIR filter functions
parameters like
uint16_t numStages
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
Well, the first hit googling "cmsis dsp software library documentation" is
http://www.keil.com/pack/doc/CMSIS/DSP/html/index.html "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.
