What is an example of decimation?

The decimation factor is usually an integer or a rational fraction greater than one. This factor multiplies the sampling interval or, equivalently, divides the sampling rate. For example, if compact disc audio at 44,100 samples/second is decimated by a factor of 5/4, the resulting sample rate is 35,280.

How do you find decimation?

The decimation factor is simply the ratio of the input rate to the output rate. It is usually symbolized by “M”, so input rate / output rate=M. Tip: You can remember that “M” is the symbol for decimation factor by thinking of “deci-M-ation”.

What do you mean by decimation by factor D explain with example?

The process of reducing the sampling rate by an integer factor(D) is called decimation of the sampling rate. It is also called down sampling by factor(D). Decimator consists of decimation filter to band limit the signal and down sampler to decrease the sampling rate by an integer factor (D).

What is decimation when it is performed?

Decimation (Latin: decimatio; decem = "ten") was a form of Roman military discipline in which every tenth man in a group was executed by members of his cohort.
