    Can anyone show me how to simplify the sum of minterms of a 4-to-2 encoder using boolean algebra?

    Most of the websites simplify it using K-Maps... I need it using boolean algebra.

    Many thanks!!

    Hi,

    Construct the truth table - the boolean will follow it.

    perhaps the link here, will help you construct that boolean equation you need without the use of the k-maps, but...the k-maps seem like a logical method to use to determine the function you're looking for.
