Is Nyquist rate and sampling rate 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 sampling and modulation?

These pulse modulation techniques deal with discrete signals. So, now let us see how to convert a continuous time signal into a discrete one. The process of converting continuous time signals into equivalent discrete time signals, can be termed as Sampling.

What is sampling frequency in amplitude modulation?

To convert a voice signal (0-3.3kHz) to digital form, the minimum sampling frequency is 6.6kHz. In practice, sampling frequency = 8kHz. To convert an audio signal (0-20kHz) to digital form, the minimum sampling frequency is 40kHz. In practice, sampling frequency for encoding music into CD is 44.1kHz.

What is the relationship between sampling rate and frequency?

Sampling rate determines the sound frequency range (corresponding to pitch) which can be represented in the digital waveform. The range of frequencies represented in a waveform is often called its bandwidth.
