Introduction on Digital Logic
Digital or Boolean Logic is a fundamental concept in modern computer systems. It helps make decisions on extremely complicated questions by basing them on relatively easier questions that can be answered by yes or no.
The digital logic circuits can be broken into subcategories: combinational and sequential. The combinational logic changes instantly, while the sequential logic has a clock signal that changes through the varying state of the circuit on the edge of the clock.
It is also important in programming as an understanding of it helps make complex decisions.
Digital Signal
A digital signal is a signal used to represent data as a finite sequence of discrete values. In most digital logic circuits, there are two types of valid values binary signal and logic signal.
