Understanding Decoders
Decoders are essential components in digital electronics, used to convert binary-coded information into recognizable outputs.
Function of a Decoder
- A decoder takes a binary input and activates one specific output line corresponding to that input.
- For instance, a 2-to-4 decoder takes 2 input bits and generates 4 unique outputs, where only one output is HIGH (active) at any time.
Types of Outputs
- Decoders are versatile and can produce outputs in various numeral systems:
- Decimal: Converts binary to base-10 numbers.
- Octal: Converts binary to base-8 numbers.
- Hexadecimal: Converts binary to base-16 numbers.
Applications of Decoders
- Used in memory address decoding in microprocessors.
- Facilitate data routing in communication systems.
- Enable control functions in complex digital systems.
Comparison with Other Options
- Demultiplexing: Distributes a single input signal to multiple outputs but does not convert binary codes.
- Multiplexing: Combines multiple input signals into one output line, which is the opposite of decoding.
- Encoder: Converts input signals from multiple sources into a binary format, essentially performing the reverse function of a decoder.
Conclusion
The correct answer to the question is option 'A' because decoders uniquely convert binary-coded information into various numeral outputs, making them indispensable in digital systems.

Decoder:
- A decoder is a combinational circuit that has ‘n’ input lines and a maximum of 2n output lines.
- Decoder converts binary-coded information to unique outputs such as decimal, octal digits, etc.
- A particular output will be active High depending upon the combination of inputs present when the decoder is enabled.
- We can, therefore, conclude that a decoder detects a particular code.
A 2 to 4 decoder is shown in the block diagram below:
Truth Table:
Application:
A decoder is used to convert a BCD code to a 7 segment code. This is explained in the following block diagram:
