If you sample at more than the Nyquist frequency (one half the signal frequency) you introduce an aliasing distortion, seen as sub harmonics.
Oversampling is part of signal processing. It is the process of using a sampling frequency that is higher than the Nyquist rate to sample a signal.
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.
The ADC10 peripheral on most MSP430s can sample at upwards of 200 ks/s.
Sample Rate. Good Luck @ Full Sail!!
It quantizes it into discrete points represented by zeros and ones (digital information). The number of samples must be at least two times the highest frequency component of the analog wave. The number of bits in each sample determines how close the digital information is to the actual value of the analog signal.
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.
It is reduced.
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
2kHz - That's the nyquist frequency at a sample frequency of 4kHz.
sample is a noun and sampling is TO sample(verb)
fs may refer to sampling frequency which is the frequecy used to sample an analog signal.
You must sample at 2 x the rate of the analog signal (2 x the analog signal frequency).
Convenience sampling or quota sampling
A sampling universe is what a sample is intended to represent.
The sampling error is inversely proportional to the square root of the sample size.
sample is a noun. sampling is a verb. Statistically speaking, a sample is where we gather and examine part of a population. A sampling is where we take the means of samples in order to gather info about the whole...
