The sampling rate is the number of samples taken from a continuous signal over a period of time (typically measured per second - Sa/s or Samples per Second).
The Nyquist - Shannon Sample Theorem states that a sample rate should be double the highest recorded frequency. Since the range of human hearing is 20Hz - 20,000 Hz, the minimum sample rate should be 40,000 Hz. CD format sample rates are 44.1kHz for this reason as well as other technical reasons.

What is the unit of measurement of the sampling rate when recording sound waves?
The sampling rate is expressed in units of either "samples per second" or "Hertz (Hz)".
What sampling rate from a sound card would you require if you want to be able to record CD sound quality?
The standard CD is two-channel 16-bit PCM encoding at a 44.1 kHz sampling rate per channel.
What unit of measure is used to express the sampling rate of a sound card?
hertz Hz
Of a sound card is the number of samples taken of an analog sound signal over a period of time?
"The sampling rate of a sound card, which is the number of samples taken of the analog signal over a period of time, is usually expressed as samples (cycles) per second, or hertz (Hz)."(Pg. 436, A+ Guide to Managing and Maintaining Your PC)
What is the sampling rate in Hz?
Sampling rate is a defining characterstic of any digital signal. In other words, it refers to how frequently the analog signal is measured during the sampling process. Compact disks are recorded at a sampling rate of 44.1 kHz.
How does sampling rate relate to the size of mp3 files?
The sampling rate affects the audio quality.For instance,a song sampled at 192 kilobits per second is three times the size of a song sampled at 64 kilobits per second and will be of better sound quality.
How does the Sampling rate affect frequency?
In signal processing, sampling is the reduction of a continuous signal to a discrete signal. A common example is the conversion of a sound wave (a continuous signal) to a sequence of samples (a discrete-time signal).
What uis the sampling rate for PCM if the Frequency ranges from 1000 to 4000 Hz?
As we know that the sampling rate is two times of the highest frequency (Nyquist theorm) Sampling rate=2 Nyquist fs=8000hz/8khz
What is sampling rate of cds?
44.1kHz
Sampling rate unit?
what is the rate unit of 1,700 and 40
What is sampling rate in audio digitization?
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 up sampling and down sampling?
Upsampling is the process of increasing the sampling rate of a signal. For instance, upsampling raster images such as photographs means increasing the resolution of the image.In signal processing, downsampling (or "subsampling") is the process of reducing the sampling rate of a signal. This is usually done to reduce the data rate or the size of the data.
