How To Make Conditional Loop Circuit Using Logic Gates

How to desgin a loop in digital electronics using counter.

Implementation using gates in proteus.

Loop Introduction -

Loop is a set of tasks in which these set of tasks executed many times.

Loop is a popular term of programming languages.

for example if you want add two numbers 10 times what you will do to perform this task.

Will you make 2 bit adder 10 times using logic gates ?

The answer is " No ".

You should use loop to solve this problem.

What we need -

1. Counter 
2. Magnitude comparator
3. Decoder

Circuit Diagram -

Use Decoder output to perform your task.

I have used only three outputs of counter and 3 to 8 line decoder. You can use all outputs of counter with 4 to 8 line decoder .
