The discrete-time signal x[n] is actually the result of sampling a periodic continuous signal x(t). The signal x[n] is 1 from -12 to +12, zero from n = 13 to 87 and then it repeats. What is the positive frequency (in hz) of the Null Bandwidth if x(t) was sampled at 8khz (telephone)? What about 44khz (CD quality)?
