Sampling rate and number of samples

The sample rate is the samples it acquire or generate in a second and the number of samples indicates the amount of signal that was acquired or generated.

What is the relationship between sampling frequency number of samples and time?

The sampling frequency or sampling rate, f_s, is the average number of samples obtained in one second, thus f_s = 1/T. Its unit is sample per second or hertz e.g. 48 kHz is 48,000 samples per second. Reconstructing a continuous function from samples is done by interpolation algorithms.

What is meant by sampling rate?

Sampling rate or sampling frequency defines the number of samples per second (or per other unit) taken from a continuous signal to make a discrete or digital signal.

What is the difference between sampling rate and sampling frequency?

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.

How does sampling rate affect 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.
