4. Why DLD? Introduction to Digital Logic Design helps in building understanding from the bottom up-starting with simple binary numbers and codes, moving through the switch, gate, and register levels, and concluding with an introduction to system architecture.

5. Analog and digital signals An analog signal has infinitely many levels of intensity over a period of time. As the wave moves from value A to value B, it passes through and includes an infinite number of values along its path. A digital signal , on the other hand, can have only a limited number of defined values. Although each value can be any number, it is often as simple as 1 and O.

7. Analog and digital signals A continuous signal can be represented digitally by taking samples at regular and fixed intervals.
