What is the relation between sampling frequency and signal frequency?
The sampling rate must be equal or superior to the double of the highest frequency or the signal .
What is the sampling frequency of a signal?
Definition: 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.
Is sampling rate and frequency the same?
The units for sample rate are samples per second (sps) or Hertz (Hz). 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.
How does sampling frequency affect signal?
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.
