If you sample at more than the Nyquist frequency (one half the signal frequency) you introduce an aliasing distortion, seen as sub harmonics.

What is the difference between sampling frequency and frequency?

frequency is simply the rate at which something is happening, ie the frequency of Christmas is once a year, the frequency of having breakfast is once a day etc. If frequency is expressed in Hertz, it's how many times something happens during a second. Sampling is, well, sampling. Usually means testing and measuring something changeable. If you're running a bath and occasionally stick your fingers in to check the temperature, then that's sampling, Sampling frequency simply describes at which rate you're making whatever test or measurement it is you're talking about.


What happens to the sampling error when the sample size is increased?

It is reduced.


If sampling frequency doubles then?

not sure what your asking, but if you are asking what i think your asking, you have to sample at least at twice bandwidth of the frequency you are sampling. This is known as Nyquist Rate http://en.wikipedia.org/wiki/Nyquist_rate


What is the difference between a sample and sampling?

sample is a noun and sampling is TO sample(verb)


What is the lowpass filter cutoff frequency that must be used to decimate to reduce the sampling rate from 8kHz to 4kHz?

2kHz - That's the nyquist frequency at a sample frequency of 4kHz.


What does fs mean on mixer?

fs may refer to sampling frequency which is the frequecy used to sample an analog signal.


What is the minimum sample rate required to record a frequency of 96 kHz?

The minimum sample rate required to record a frequency of 96 kHz is 192 kHz. This is because according to the Nyquist theorem, the minimum sampling rate must be at least twice the highest frequency in order to accurately reconstruct the original signal. So for a frequency of 96 kHz, the minimum required sampling rate is double, which equals 192 kHz.


What does the sampling theorem tell us concerning the rate or sampling required for an analog signal?

You must sample at 2 x the rate of the analog signal (2 x the analog signal frequency).


What type of sampling (sample strategy) is it when I am sampling employees from different organizations?
