Introduction to Digital Systems


Digital system processes discrete values of information. Today digital systems are used in every application, communications, military, consumer electronics, medical electronics, computers and so on.
Advantages of digital systems:
·         Effect of noise is less on digital signal
·         Programmability
·         Storage is easy
·         Many components of digital circuits can be fabricated on IC
·         Size, cost and power consumption is less

Disadvantages of digital systems:
·         Practical signals are analog in nature
·         Quantization noise conversion from analog to digital. Accuracy is less compared to analog
