SUMMARY
A signal sampled from a periodic signal is not inherently periodic unless the sampling frequency is an exact multiple of the original signal's frequency. This relationship establishes that while periodic signals maintain their characteristics under certain conditions, the general outcome of sampling does not guarantee periodicity. The discussion emphasizes the importance of understanding the sampling frequency in relation to the original signal's time period.
