is a cic filter stable
Hi FvM,
I am using this filter to reduce the frequency sampling rate.
Do you think i can use different filter structure to reduce the group delay of the FIR filter?
For example, let's talk about a simple low pass 4 tap FIR filter and use direct form structure to implement this filter.
Is there any different if i use a serial multiplication and parallel multiplication? that mean for serial multiplication, i need to run 4 multiplication on 4 clock delay before i get a new output. And for parallel multiplication, i run 4 multiplication on each clock and output a new value on each clock.
Thanks.
