Question

A signal is expected to be bandlimited to 100 hz, with significant components of interest upto 80 hz. however, the signal is contaminated with a periodic artifact with fundamental frequency of 60 hz and significant third and fifth harmonics. a researcher samples the signal at 200 hz without pre- filtering the signal. draw a schematic representation of spectrum of signal and indicate the artifact components.
