JEE Main 2021 (Online) 26th August Evening Shift Physics - Semiconductor Question 98 English Explanation

y=(A+A+B‾‾)+(B+A+B‾‾)‾y = \overline {(\overline {A + \overline {A + B} } ) + (\overline {B + \overline {A + B} } )}

y=(A+A+B‾).(B+A+B‾)y = (A + \overline {A + B} ).(B + \overline {A + B} )

A B y
