Match the digital logic circuits in Column A with their correct functional descriptions in Column B: Column A Column B A. Decoder I. Select input and output of many B. Multiplexer II. Convert binary input into output C. Encoder III. Convert input into binary output D. Demultiplexer IV. Route one input to several output

(A)-I, (B)-II, (C)-III, (D)-IV Explanation: Solution To match these correctly, we look at the primary function of each combinational circuit: A. Decoder: A decoder is a circuit that changes a code into a set of signals. It takes binary input lines and activates one of the output lines. Logic: lines. Match: (A) — II B. Multiplexer (MUX): Also known as a "Data Selector," it has many inputs and only one output. It selects one of many inputs based on select lines and steers it to the output. Logic: Many-to-One. Match: (B) — I C. Encoder: This is the functional inverse of a decoder. It receives (or fewer) input lines and converts them into an -bit binary code. Logic: lines. Match: (C) — III D. Demultiplexer (DEMUX): Also known as a "Data Distributer," it takes a single input signal and routes it to one of several output
