prøvetakingsfrekvensen

Prøvetakingsfrekvensen, also known as sampling frequency, is a fundamental concept in the field of signal processing and digital communications. It refers to the number of times per second that a signal is sampled or measured. The sampling frequency is typically denoted by the symbol fs and is measured in Hertz (Hz).

The Nyquist-Shannon sampling theorem is a crucial principle that governs the relationship between the sampling frequency

In practical applications, the sampling frequency is chosen based on the characteristics of the signal and

The choice of sampling frequency can have significant implications for the performance of a system. A sampling
