A 3-to-8 line decoder with inputs A, B, and C (where A is MSB) has active-high outputs Y0 to Y7. If outputs Y1, Y3, Y5, and Y6 are connected to an OR gate, the output function F(A, B, C) of the circuit is expressed as:
- 1F(A,B,C) = Σ m(1,2,3,5,7)
- 2cannot be determined because of inadequate data
- 3F(A,B,C) = Σ m(1,3,5,6)✓
- 4F(A,B,C) = Σ m(0,2,4,6)
Correct answer
F(A,B,C) = Σ m(1,3,5,6)
