Final answer:
A decoder is a digital electronics device that undeniably translates a binary input to a unique binary output, detailed through a truth table which shows all input and output combinations.
Step-by-step explanation:
A decoder in digital electronics is a device that converts a binary input code to a unique binary output code. Decoders are used extensively in various applications such as data multiplexing, 7-segment display, and memory address decoding. The operation of a decoder is typically represented in a truth table, which lists all possible input combinations and their corresponding unique output combinations. For instance, a 2-to-4 line decoder has two input lines and four output lines. Its truth table will show that for each binary input (00, 01, 10, 11), there is a unique output line that goes 'high' (1), while the others stay 'low' (0).
One common application of decoders is in memory systems where the decoder is used to select the correct memory address based on the input address lines. Each unique output corresponds to one memory location, ensuring that the correct memory cell is accessed for reading or writing dataIn digital electronics, a decoder is a combinational logic circuit that takes an input code and produces a unique output based on that code. It is commonly used to convert coded information into a form that can be easily understood or used by other parts of a system. A truth table is a tabular representation of a decoder's behavior, showing the outputs for all possible input combinations.
