In conclusion, both analog and digital communication systems have their own strengths and weaknesses. Analog systems are simple to implement and cost-effective but are susceptible to noise and have limited capacity. Digital systems, on the other hand, offer high noise immunity and capacity but are more complex to implement and expensive.

Sanjay Sharma is unique because he refuses to treat analog and digital as separate subjects. In the preface of his book, he notes: "Digital communication is merely analog communication with discrete amplitudes." : Includes dedicated chapters on Information Theory, Error
