1. Introduction
Sampling is essential to convert analog signal to digital signal. In this page, I would specifically explain about down sampling.
In digital signal processing, the decimator performs decimation, which is down sampling a signal. In other words, when a digital
signal is down sampled, the signal's sampling rate would be reduced.
