Question

If the interpolation factor is I = 256, the A/D converter output can be obtained by averaging successive non-overlapping blocks of 128 bits.

(a) True

(b) False

This question was posed to me in an international level competition.

My doubt is from Sample and Hold topic in division Sampling and Reconstruction of Signals of Digital Signal Processing

Answer 1

Right choice is (a) True

For explanation: If the interpolation factor is I = 256, the A/D converter output can be obtained by averaging successive non-overlapping blocks of 128 bits. This averaging would result in a digital signal with a range of values from zero to 256 (b as 8 bits) at the Nyquist rate. The averaging process also provides the required anti-aliasing filtering.
