What is the purpose of a decoder in digital circuits? a. Converts digital signal to analog b. Converts one binary code into several output lines c. Converts analog signal to digital d. Converts one output line into several binary codes e. None of them

The correct answer is b. Converts one binary code into several output lines.<br /><br />A decoder in digital circuits is a device that takes in a binary code (input) and converts it into several output lines. It acts as a demultiplexer, where each input code corresponds to a specific output line. This is useful in various applications such as memory addressing, data routing, and control signals in digital systems.
