Here we design a simple display decoder circuit using logic gates. Even though commercial BCD to 7 segment decoders are available, designing a display decoder using logic gates may prove to be ...

The HEF4543B is a BCD to 7-segment latch/decoder/driver for liquid crystal and LED displays. It has four address inputs (D0 to D3), an active LOW latch enable input (LE), an active HIGH blanking input ...

In the project, it is aimed to design a BCD multiplier that multiplies a 2-digit BCD number with a 1-digit BCD number and returns the result as 3-digit BCD number. In addition, a seven-segment decoder ...

Now-a-days majority of practical applications such as valet car parking, larger temples necessitate, seven segment displays to give a visual token of the numbers. Digital counters are the one which ...

The display is multiplexed: so be careful if you are going to modify anything if you build this because it has to run on a loop with continuous and fast timing to run the BCD decoder to keep the ...
