- 4. What is Encoders& Decoders? An encoder is a device that converts data from one format to another. A decoder is a logic circuit that converts coded inputs into coded outputs.
- 5. Importance in digital electronics Digitalelectronics are more important than analog electronics because they are more accurate, reliable, and energy efficient. Digital signals are less capable to noise and interference, making them more reliable in transmission mediums like satellite TV and cell phone networks. Digital data is also more compact and less likely to be corrupted, making it easier to store and maintain over time.

- 14. Binary to OctalDecoder A B C Figure : Block Diagram A Binary-to-Octal decoder has three input lines and eight output lines. When a 3-bit input code is applied to the decoder, one of the 8 output lines corresponding to that input code is activated. This decoder is also called a 3-line-to-8-line decoder or 1-of-8 decoder. Its truth table is given below.

- 19. Encoders and Decodersin Memory Systems Memory Address Decoding Purpose: Translates a memory address (provided by the CPU) into a specific location within the memory chip where data is stored or retrieved. Decoder's Role: A decoder circuit selects one particular memory location out of many based on the address bits.
- 20. RAM and ROMAccess Control Encoders: In some systems, encoders may be used to generate control signals that enable or disable access to specific memory chips or regions. Decoders: Primarily responsible for decoding memory addresses, but they can also be involved in generating timing and control signals for memory access.
- 21. Conclusion The Future ofEncoders and Decoders As technology advances, so too will the complexity and sophistication of the encoding and decoding schemes employed. Look for continued innovation in areas like error correction, data compression, and encryption, as we strive to achieve faster, more reliable, and more secure communication and data storage systems.
