Digital circuit examples
There are seven basic logic gates: AND, OR, XOR, NOT, NAND, NOR, and XNOR.
The AND gate is so named because, if 0 is called "false" and 1 is called "true," the gate acts in the same way as the logical "and" operator.
The following illustration and table show the circuit symbol and logic combinations for an AND gate..
Fundamentals of digital Electronics
Course Objectives
Be able to design and analyze sequential logic circuits.

Fundamentals of digital Electronics
Digital Circuits are designed using logic gates, diodes, transistors, inductors, capacitors, and resistors.
As Digital Circuits follow Boolean Laws, the logic expressions should be simplified for a small circuit.
Small the digital circuit, the easier for it to be embedded in Integrated Circuits (ICs)..
How do you analyze logic circuits?
To analyse the behaviour of a logic circuit a truth table can be used.
As well as the inputs and the output, extra columns are added for the intermediate points in the logic circuit.
Note: Logic circuits can also be analysed using Boolean Algebra or Karnaugh Maps but this page only considers basic truth tables..
How does digital logic design work?
Digital Logic is rooted in binary code, a series of zeroes and ones each having an opposite value.
This system facilitates the design of electronic circuits that convey information, including logic gates.
Digital Logic gate functions include and, or and not..
What are the steps in logic design?
General design procedure for combinational logic
- Understand the problem
. what is the circuit supposed to do? .- Formulate the problem using a suitable design representation
. truth table or waveform diagram are typical.- Choose implementation target.
ROM, PAL, PLA.- Follow implementation procedure.
K-maps for two-level, multi-level.

What is the function of an AND gate?
An AND gate is an electrical circuit that combines two signals so that the output is on if both signals are present.
The output of the AND gate is connected to a base driver which is coupled to the bases of transistors, and alternately switches the transistors at opposite corners of the inverter..
