A signal is bandlimited to 12 kHz. The band between 10 and 12 kHz has been so
Question:
A signal is bandlimited to 12 kHz. The band between 10 and 12 kHz has been so corrupted by excessive noise that the information in this band is non-recoverable. Determine the minimum sampling rate for this signal so that the uncorrupted portion of the band can be recovered. If we were to filter out the corrupted spectrum prior to sampling, what would be the minimum sampling rate?
Understand aliasing. From wikipedia: “In signal processing and related disciplines, aliasing is an effect that causes different signals to become indistinguishable (or aliases of one another) when sampled. It also refers to the distortion or artifact that results when the signal reconstructed from samples is different from the original continuous signal.”
