Minimum Sampling Frequency and the Nyquist Theorem
The minimum frequency of sampling required to adequately express an analog waveform is known as the Nyquist frequency. The Nyquist theorem states that in order to accurately reconstruct a continuous signal from its samples, the sampling frequency must be at least twice the highest frequency component present in the signal.
Explanation:
- When an analog waveform is sampled, it is converted into a discrete-time signal by taking samples at regular intervals.
- The process of sampling involves measuring the amplitude of the waveform at specific points in time and converting it into a digital representation.
- The sampling rate or sampling frequency refers to the number of samples taken per unit of time.
- The Nyquist frequency, also known as the Nyquist rate, is the minimum sampling frequency required to prevent aliasing and accurately represent the original analog waveform.

What is the minimum frequency of sampling so that the analog waveform ...
The minimum frequency at which an analog wave should be sampled is given by Nyquist frequency. If the sampling frequency is below this limit then the analog waveform is not fully represented and leads to data loss.
