Write the truth table to realize the function nand gate, Computer Engineering

Assignment Help:

For F = A.B.C + B.C.D‾ + A‾.B.C, write  the  truth  table to realize the function using NAND gates only ?

Ans. Logic Function given as F = ABC + BC‾D + A‾BC, simplification of this expession isgiven below:
