Digital logic is the key to much of modern electronics. Digital watches, clocks, counters, timers, calculators and computers are all designed with digital logic. Analog electronic circuits can process a wide range of voltages. Digital logic processes only two voltage levels, one of which is at or near ground (0 volt or the low logic state} and the other being near or at the circuit's supply voltage (high logic state). The two logic levels or states of digital logic circuits allow them to represent "yes" and "no" or "on" and "off". This means that digital logic circuits can make decisions. The two logic states can also represent 0 (low) and 1 (high). The two digits of the binary number system. This means that digital logic circuits can perform arithmetic, process instructions and store information.
