What is the frequency response of the analog filter corresponding to the ideal interpolator?
(a) H(F)=\(\begin{cases}T, |F|≤ \frac{1}{2T} = F_s/2\\0,|F| > \frac{1}{4T}\end{cases}\)
(b) H(F)=\(\begin{cases}T, |F|≥ \frac{1}{2T} = F_s/2\\0,|F| > \frac{1}{4T}\end{cases}\)
(c) H(F)=\(\begin{cases}T, |F|≤ \frac{1}{2T} = F_s/2\\0,|F| > \frac{1}{2T}\end{cases}\)
(d) H(F)=\(\begin{cases}T, |F|≤ \frac{1}{4T} = F_s/2\\0,|F| > \frac{1}{4T}\end{cases}\)
I had been asked this question by my college professor while I was bunking the class.
I'd like to ask this question from Digital to Analog Conversion Sample and Hold in portion Sampling and Reconstruction of Signals of Digital Signal Processing
