Question

logic gates diagram of y=A'B'C'D + AB'C'D + ABC'D + ABCD' step by step with truth table.​

Answer 1

Answer:

The output state of a digital logic AND gate only returns “LOW” again when ANY of its inputs are at a logic level “0”. In other words for a logic AND gate, any LOW input will give a LOW output.

ADVERTISING

The logic or Boolean expression given for a digital logic AND gate is that for Logical Multiplication which is denoted by a single dot or full stop symbol, ( . ) giving us the Boolean expression of: A.B = Q.

Then we can define the operation of a digital 2-input logic AND gate as being:

“If both A and B are true, then Q is true”

2-input Transistor AND Gate

A simple 2-input logic AND gate can be constructed using RTL Resistor-transistor switches connected together as shown below with the inputs connected directly to the transistor bases. Both transistors must be saturated “ON” for an output at Q.
