Therefore, in modern electronic systems, engineers use logical high voltage and logical low voltage (ground) to represent signals 1 and 0, so as to convert the binary mathematical structure into the electronic system, which is the digital signal. Digital signals are widely used in computing, storage and other fields, and the integrated circuit used to process digital signals is IC digital.
ic stands for digital signal. A digital signal is a signal in which the independent variable is discrete and the dependent variable is discrete. The independent variable of such a signal is represented by an integer, and the dependent variable is represented by a number in a finite number. In computers, the size of a digital signal is often represented by a finite binary number.
