Nyquist zone frequency calculator can be used to determine the Nyquist frequency, which is half of the sampling rate, for a given sampling rate. This is essential in ensuring that the sampled signal is accurately represented without aliasing.

The Nyquist frequency is the minimum rate at which a continuous signal must be sampled to avoid aliasing. According to the Nyquist-Shannon sampling theorem, to properly sample a signal, the sampling rate must be at least twice the highest frequency present in the signal.
If your sampling rate is 1000 Hz, the Nyquist frequency would be 500 Hz. This means that frequencies above 500 Hz could cause aliasing if not properly filtered before sampling.
Ensuring that your sampling rate is at least twice the highest frequency of the signal you are capturing is crucial for accurate representation. Failure to do so can result in aliasing, where higher frequencies are incorrectly represented as lower frequencies.
