The Nyquist rate is the minimal frequency at which you can sample a signal without any undersampling. It's double the highest frequency in your continous-time signal. Whereas the Nyquist frequency is half of the sampling rate.

Is Nyquist rate and Nyquist frequency same?
The Nyquist rate is 2x the given frequency to be measured accurately. The theorem can be used in reverse. The Nyquist frequency is the highest frequency that equipment of a given sample rate can reliably measure, one-half the given sample rate. The Nyquist theorem is an important part of information theory.
What is meant by Nyquist rate?
In signal processing, the Nyquist rate, named after Harry Nyquist, is a value (in units of samples per second or hertz, Hz) equal to twice the highest frequency (bandwidth) of a given function or signal.
What is Nyquist rate and Nyquist interval?
When the sampling rate becomes exactly equal to 2fm samples per second, then it is called Nyquist rate. Nyquist rate is also called the minimum sampling rate. It is given by, Similarly, maximum sampling interval is called Nyquist interval.
Is sampling rate and sampling frequency same?
The two are equivalent since the Hertz is equal to the reciprocal second, [Hz]=[s-1]. Hertz is the unit for frequency, and the sample rate is sometimes referred to as the sampling frequency. Sample rate and sampling frequency represent the same value.
