Which of the following is the disadvantage of sampling rate conversion by converting the signal into analog signal?(a) Signal distortion(b) Quantization effects(c) New sampling rate can be arbitrarily selected(d) Signal distortion & Quantization effectsI had been asked this question in unit test.This intriguing question comes from Multirate Digital Signal Processing in section Multirate Digital Signal Procesing of Digital Signal Processing

Answer»

Right ANSWER is (d) Signal distortion & Quantization effects

Easiest EXPLANATION: The major disadvantage by the GIVEN type of CONVERSION is the signal distortion introduced by the D/A CONVERTER in the signal reconstruction and by the quantization effects in the A/D conversion.
