Sampling Rate

The sampling rate is the number of samples per unit of time taken from a continuous signal to convert it into a digital format.

Example: The sampling rate of a CD is 44,100 samples per second.

Senses and Usages:

1. Audio and Sound Engineering

In audio and sound engineering, the sampling rate refers to the rate at which an analog audio signal is converted into a digital format.

Example: To ensure high-quality audio recordings, professionals often use a sampling rate of 96 kHz.

2. Digital Imaging

In digital imaging, the sampling rate is the number of pixels captured per unit of distance to create a digital image.

Example: The higher the sampling rate of a digital camera, the more detailed and sharper the resulting image.

3. Signal Processing

In signal processing, the sampling rate refers to the rate at which a continuous time signal is sampled to obtain a discrete time representation.

Example: To accurately reconstruct a signal, the sampling rate must be at least twice the highest frequency in the signal according to the Nyquist-Shannon sampling theorem.
