Thank you very much.....

* circuit 95 liven logic diagram as Where A, B, C are are inputs, output. X that | Do output ex We know & outfut AND GATE output = B *C NOR GATE X = A + BC in X . values A, B,C . Substitute

→ Logic Table : BTC output - - - ooo 0 0 - - Oo - - o DO - 0 - 0 - 0 0 lio 0 ll! 0 0 0 * circuit 10 : mare for output as get expression x= ñ +(6+C)] —®

Substitute A, B, C values in @ - Sogic Table : ABC output x Cooo 0 - - - 200 -- 0 0 - - 0-0-0 -0- -ooooooo * – Circuit Logic ll: Diagram is A x output is expression for = A * (8+) — ®

- Substitute A, B, C in 3 Logic Table output x ----Ooooo ooo - - o Uo-o-o-o - - - - oooool - circuit 12 : Logic Diagram is not gate s A - Empression x= for culpul is A*(B+C) = A+Btc

— o o o o |» Logic substitute x= — — o o - - оо - о - о - о - оо Table A, B, C AtBtc : o o o o ooo - I output x values in — x .
