Lesson 16 Challenge 15 Challenge An N+1=11 order comb filter has an impulse response  h[k]={1,0,0,0,0,0,0,0,0,0,0,1} and is clocked at a rate of f s =1MHz.   What are the filter’s null frequencies? Response The FIR’s frequency response is given by: H(e j ω )= e j0 ω  + e -j11 ω  = 1 + e -j11 ω

Lesson 16 Challenge 15 The zeros correspond to those frequencies  ω  that set the term H(ej ω )= 1 + e - j11 ω  to zero.   The positive baseband frequencies are  ω ± { π /11, 3 π /11, 5 π /11, 7 π /11, 9 π /11, 11 π /11}  or frequencies of  f =  ± {1/22, 3/22, 5/22, 7/22, 9/22, 11/22}f s .   Simulation: >> h= [1 0 0 0 0 0 0 0 0 0 0 1 zeros(1,1000)]; >> freqz(h,1)
