What is the expression for an AND gate?

AND gate. An AND gate can be used on a gate with two inputs. The Boolean expression is written as Q = A AND B.

How do you draw a waveform for a logic gate?

In order to determine the proper output waveform from a logic gate, simply divide the input diagrams into time segments where the inputs are constant and determine the state of the output (high or low) for that segment from the truth table.

How is an AND gate constructed?

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.

What is a logic gate simple definition?

A logic gate is a device that acts as a building block for digital circuits. They perform basic logical functions that are fundamental to digital circuits. Most electronic devices we use today will have some form of logic gates in them.

How do you find the Boolean expression of an OR gate?

The Boolean expression of OR gate is Y = A + B, read as Y equals A ‘OR’ B. The truth table of a two-input OR basic gate is given as;

How to describe the operation of a logic gate?

The operation of any logic gate or combination of gates can be described using Boolean algebra. In this section, we will look at Boolean algebra of the basic gates already discussed and address the basic Boolean rules (laws).

What is the schematic representation of an AND gate?

The schematic representation of an AND gate in digital circuits is: A and B are the inputs to the gate, and X is the corresponding output. The next gate we will investigate is the operation of the OR gate. OR gate operation is similar to a basic parallel circuit as shown in Figure 2 below.

How do you evaluate the expression “B(A + C)”?

In this case, we would begin with the sub-expression “A + C”, which is an OR gate: The next step in evaluating the expression “B (A + C)” is to multiply (AND gate) the signal B by the output of the previous gate (A + C): Obviously, this circuit is much simpler than the original, having only two logic gates instead of five.
