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.

What is targeted sampling in research studies?
I would like to sample the signal Xa(t) =1+cos(10 *pi*t) using sampling frequency fs=8 Hz. How can I calculate this? ANSWER: Your signal has a frequency component of 5hz (from the equation: 2*pi*f*t = 10*pi*t, therefore f=5). The Nyquist rate for this signal (the minimum sampling rate required to reconstruct the signal) is then 10Hz, and even at that rate the amplitude of the sampled signal will be reduced unless you can somehow synchronize the sampling with the peaks/troughs of the cosine signal. If you sample at 8Hz you will not be able to reconstruct the signal at all.
Sampling rate unit?
what is the rate unit of 1,700 and 40
What is differences between convenience and incidental sampling?
The difference between convenience and incidental sampling is that convenience sampling chooses the easiest people to reach when a sampling is done, whereas incidental sampling is done at random.
What is the difference between random sampling and non random sampling?
a
What is scientific sampling?
sampling is when you take a peice of somthing and test it.
What is the sampling rate in Hz of music CDs?
44,100 Hz or 44.1 KHz
If the frequency spectrum of a signal has a bandwidth of 500 Hz with the highest frequency at 600 Hz what should be the sampling rate?
The Nyquist Therorem states that the lowest sampling rate has to be equil to or greather than 2 times the highest frequency. Therefore the sampling rate should be 400Hz or more.
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 is the sampling rate for PCM if the Frequency ranges from 1000 to 4000 Hz?
>8000hz
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 the sampling rate of music CDs?
44,100 Hz or 44.1 kHz
What unit of measure is used to express the sampling rate of a sound card?
hertz Hz
What is sampling rate in sound?
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.
State and prove the sampling theorem?
If the signal is bandwidth to the fm Hz means signal which has no frequency higher than fm can be recovered completely from set of sample taken at the rate
What is the difference between sample size and sampling rate?
Rate refers to frequency, while size refers to the amount. Thus, Sampling Rate is measured in Hertz (number of times per second a sample is taken), and Sampling Size is measured in Bits (number of binary digits of information taken at a single time). Thus, if you Sample at 10 Hz/8 bits, that means you take 8 bits of information, 10 times per second.

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)
