How to design IIR digital filters?

One more bit of information that is needed: the damping or Q-factor of the poles so that the continuous impulse response can be obtained. It is sometimes useful to model a continuous-time filter in a ...

How to design IIR digital filters?

An approach to design IIR filters without mapping from classical analog designs is the least squares method where the poles and zeros are selected within a constraint of filter order and targets for ...

Question about reducing phase delay in filters for microcontroller application

You can't do better than a minimum phase filter. A first order IIR filter will have a phase of -45 degrees at the crossover, so getting to less than -15 degree at 320 Hz will be tricky. Turns out at ...
