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.

What is the purpose of decimation?

Decimation reduces the original sample rate of a sequence to a lower rate. It is the opposite of interpolation. decimate lowpass filters the input to guard against aliasing and downsamples the result.

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.

What is RF decimation?

• Decimation decreases the sample rate of a signal by. removing samples from the data stream. • Decimation includes digital low pass (anti-aliasing) filter. followed by a decimator.
