What is a Digital Circuit?
A digital circuit is a circuit that functions on a number of different logic gates. The logic gates differentiate power signals. The power signals are then transferred to different parts of the digital circuit through other gates to create an output signal directly pertinent to the energy level at the moment of signal input. Most digital circuits are comprised mainly of smaller analog components that, because of the logic gate occurrence, only operate within a certain frame of voltages. Usually these operate at extremely low voltage signals. Digital circuits also require that the analog components located throughout the circuit not be placed in a manner that will allow them to perform analog functions. This usually means there is a logic gate both before and after the analog component.
