Although there many be thousands of digital decisions, they are all simple and can be handled by a limited number of digital building blocks . Greater circuit density and precision than analog. Great processing speed. Information can be easily stored. Noise can be rejected more easily.
Signals are easy to recognize and regenerate.
Disadvantages of Digital Techniques Increased processing complexity. Information transmission speed is usually lower than analog. The Design of a Two-Bit Multiplier The Problem to design a circuit that will multiply two binary numbers which are 2 bits in length.
