1. Describe two key difference between digital control systems and their analog counterparts. Your answer should include both a block diagram and a discussion on key design choices in each topology.

Expert Solution

Digital Control Systems

Digital control systems deal with binary or discrete signals having values 1 or 0.
Their input-output relationship (also called as transfer function) are represented by difference equation in z-domain.
It uses Fourier Analysis,z-transform,DFT transform techniques.
Noise,interference and distortion is comparatively less in case of digital control systems.
Power efficiency is more.
Storage , analysis and processing of data is easy and convenient.

Analog Control Systems

They deal with continuous signals that can take a wide range of values.
The transfer function is given by differential equation in s-domain.
It use Laplace Transform techniques.
Noise , interference and distortion is comparatively more.
Power efficiency is comparitively less (because of continuous signals).
Storage , analysis and processing of data is a bit complicated.
