Question 1
Digital ElectronicsDecoder Applications
To implement an arbitrary Boolean function of n input variables directly with a decoder and an OR gate, the decoder normally requires how many output minterm lines?
Correct Answer: C. 2^n
Explanation: An n-to-2^n decoder generates one output for each possible input minterm. The required minterm outputs can then be ORed to realize an SOP function.
