October 3, 2018

A comparator is a combinational logic circuit that compares input bits and gives an output that indicates the equality/inequality of a digital circuit.

multiplier - 2-bit 3-bit digital

Multiplier – Designing of 2-bit and 3-bit binary multiplier circuits

October 4, 2018

To multiply binary digits we need a special digital circuit called a multiplier. Let’s understand some multiplication rules and design the third most important arithmetic logic circuit that we will study in this digital electronics course.

4-bit parallel adder and 4-bit parallel subtractor

4-bit parallel adder and 4-bit parallel subtractor – designing & logic diagram

October 2, 2018

In digital electronics, if you have more than two or three bits of data to add or subtract, a full adder or a full subtractor won’t suffice. To add and subtract two four-bit numbers we use parallel adders and parallel subtractors.
