Show that if h[n] is an N-point FIR filter such that h[n] = h[N 1
Question:
Show that if h[n] is an N-point FIR filter such that h[n] = h[N – 1 – n] and H(z0) = 0, then H(1/z0) = 0. This shows that even symmetric linear-phase FIR filters have zeros that are reciprocal images. (If h[n] is real, the zeros also will be real or will occur in complex conjugates.)

Teaching was always an area where I can pursue my passion. I used to teach my friends and junior during my school and college life. After completing my professional qualification (chartered accountancy) and before joining my job, I also joined an organization for teaching and guidance to my juniors. I had also written some articles during my internship which later got published. apart from that, I have also given some presentations on certain amendments/complex issues in various forms.
