What is decimation in Simulink?

The Decimation parameter enables you to display data at every n th sample, where n is the decimation factor. The default decimation, 1, displays data at every time step. The Sample time parameter enables you to specify a sampling interval at which to display points.

What is decimation of clock block in Simulink?

Decimation — Interval at which to update block icon. 10 (default) | positive integer. Specify the interval at which Simulink^® updates the Clock icon as a positive integer. Suppose that the decimation is 1000. For a fixed integration step of 1 millisecond, the Clock icon updates at 1 second, 2 seconds, and so on.

How do you decimate data 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) .

What is a decimation filter?

Decimation filters help you remove the excess bandwidth and reduce the sampling frequency of the signal. Decimation filters also help you reduce the computational resources required for processing and storing the signal.
