✴ A digital circuit is a circuit where the signal must be one of two discrete levels. Each level is interpreted as one of two different states (for example, on/off, 0/1, true/false). Digital circuits use transistors to create logic gates in order to perform Boolean logic. This logic is the foundation of digital electronics and computer processing. ✴ ►Digital circuits are less susceptible to noise or degradation in quality than analog circuits. It is also easier to perform error detection and co
