Logic gates

Basic gates There are three basic gates in digital electronics. These are NOT gate, AND gate & OR gate. NOT gate / Inverter: NOT gate is called inverter also. Operation of NOT gate is if input is high output is low and if input is low then output is high. Another words output is always […]

Boolean algebra is a means for expressing the relationship between a logic circuit’s inputs and outputs. Digital circuits called logic gates circuits can be constructed from diodes, transistors and resistors connected so that the circuit output is the result of a logic operation (OR.AND, NOT). A truth table is a means for describing how a […]
