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 downsampling a signal. In other words, when a digital signal is downsampled, the signal's sampling rate would be reduced.
