Digital Design #07 | NAND and NOR as Universal Gates

Instructor: Dr. Süleyman Burak ÇELİK

In this seventh Digital Design lesson, we prove why NAND and NOR are universal gates by rebuilding NOT, AND, and OR from a single gate family. Then we implement a complete Boolean function with three NAND gates and verify every input row. In this video: - What functionally complete means - NOT from tied NAND or tied NOR inputs - AND using two NAND gates - OR using two NOR gates - Worked example: F = A.B + C using NAND only - Full eight-row expression and circuit verification Topics: 00:00 One gate family, every Boolean function 00:03 Functional completeness 00:43 Build NOT by tying inputs 01:13 Recover AND and OR 01:55 Worked NAND-only circuit 02:42 Truth-table QA 03:27 Reusable workflow and recap Next lesson: combinational blocks, beginning with decoders and encoders. #DigitalDesign #NAND #NOR #UniversalGate #BooleanAlgebra #LogicGates #LogicDesign #AcEdumy #Engineering
