This article provides a general understanding of what DSP is, how it works, and what advantages it can offer. To appreciate the advantages of DSP, let’s first have a look at the conventional method of signal processing, i.e., analog signal processing.

In this article, we discuss another methodology of how to model ADCs in system simulations, this time by using the effective number of bits and also adjusting our ADC by introducing a 5th order polynomial to the ideal quantizer input.
