A Question on FIR filter
Hi, all
I have encountered a FIR filter question couple days ago.
A guy gave me an impulse response of a FIR filter(z transform equation), and ask me to plot the bode plot of it.
I am confused about the question, isn't bode plot is the magnitude and phase response of the loop gain(AB). Since the FIR filter doesn't have feedback factor(not IIR), how can i plot the bode plot?
is B=0? and bode plot go infinite?
or B=1, Bode plot of a FIR filter is the same as it's magnitude and phase response with logged frequency axis?
thanks:?:
