Encoding is the process of representing the permissible values by a word (for example, 16 bits).

• A. Converting an analog signal to digital
• B. Representing permissible values by a word
• C. Filtering the signal
• D. Modulating the signal

Answer: (B)

Encoding is about turning a finite set of permissible values into a binary code word. In digital systems, each allowable value is assigned a unique bit pattern, and a 16-bit word simply means the pattern is 16 bits long, allowing 2^16 distinct values. This shows encoding as representing values by a code word. In contrast, converting an analog signal to digital refers to the A/D process that includes sampling and quantization before encoding; filtering removes parts of the signal, and modulation prepares a signal for transmission.
