How do you do 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 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.
Is decimation same as down-sampling?
Decimation is the process of reducing the sampling frequency of a signal to a lower sampling frequency that differs from the original frequency by an integer value. Decimation also is known as down-sampling.
How do you decimate a signal in Matlab?
y = decimate( x , r ) reduces the sample rate of x , the input signal, by a factor of r . The decimated vector, y , is shortened by a factor of r so that length(y) = ceil(length(x)/r) .
