The Nyquist frequency is achieved by sampling at least how many times per cycle?

Explanation:
Two samples per cycle. The Nyquist criterion says you must sample at least twice the highest frequency in the signal. That means for every cycle of the highest-frequency component, you need at least two samples to capture the waveform and allow faithful reconstruction. Sampling fewer than two per cycle leads to aliasing, where higher frequencies can masquerade as lower ones. Sampling exactly two per cycle is the minimum to reach the Nyquist limit, while more samples per cycle improve accuracy and reduce potential reconstruction errors.
