Learn how to use logic gates and circuit diagrams to create a simple calculator that can perform addition and subtraction with four-bit numbers.

A display decoder is used to convert a BCD or a binary code into a 7 segment code used to operate a 7 segment LED display. Here we design a simple display decoder circuit using logic gates.

We have designed a 4-Bit BCD Adder using the 7-Segment display in Proteus 8.0 Professional. It takes the two 4-Bit numbers preferably BCD (0-9) and displays the summation of inputs using 7-Segment ...

A new dual sustaining driver using two different energy recovery circuits (ERCs) for large-sized plasma display panels (PDPs) is proposed. The proposed sustaining driver has two H-bridge inverters to ...
