What is the difference between analog and digital signals?
Analog signals are continuous where digital signals are discrete. Anolog signals are continuously varying where digital signals are based on 0’s and 1’s (or as often said——- on’s and off’s). As an analogy, consider a light switch that is either on or off (digital) and a dimmer switch (analog) that allows you to vary the light in different degrees of brightness. As another analogy, consider a clock in which the second hand smoothly circles the clock face (analog) versus another clock in which the second hand jumps as each second passes (digital). Digital computers work with a series of 0’s and 1’s to represent letters, symbols, and numbers. In addition, numbers are represented by using the binary code (where only 0’s and 1’s are used).
