Hallo Everybody,
I'd like to ask about FIR filter coefficients, I am using "firceqrip"
command. I get all the coeff. in positive value, i.e., the impulse response is
only positive values.
I'd like to knoe if it is practically to implement such a filter?
What is the difference between to have all the coeff. positive or to have it
mix between positive and negative.
Thanks in advance.
