  • Because digital logic is usually implemented in terms of ones and zeros, with ones being represented by some positive voltage such as 5 v or 3.3 v, and zeros being represented by zero voltage, such circuits must quickly change state from a positive voltage to zero voltage millions or billions of times per second to provide the capability to quickly calculate or process information.
