Do you have solution for this Question. If yes    I aslo want solution.


Design a logic circuit that takes a four digit binary input, counts the

number of 1s in it, and produces it as the output. For example, if the

input is 1101, then output will be 11 (as there are three ones in the

input). Draw the truth table and use K-map to design the Boolean

expressions for each of the output bits. Draw the resulting circuit

diagram using AND – OR – NOT gates.
