1. Introduction
Sampling is essential to convert analog signal to digital signal. In this page, I would specifically explain about downsampling.
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.
2. Derivation
3. Example
4. Conclusion
