What does an Encoder do?Question 5Answera.Combines multiple inputs into one outputb.Expands a single input to multiple outputsc.Converts data from analog to digital formd.Performs arithmetic operations on multiple inputs

An encoder is a device that converts data from one format to another. In the context of the options provided:

a. Combines multiple inputs into one output - This is partially correct. An encoder can take multiple input signals and convert them into one output code. This is often used in digital systems to reduce the number of data lines.

b. Expands a single input to multiple outputs - This is typically not the function of an encoder. A device that performs this function is more commonly referred to as a decoder.

c. Converts data from analog to digital form - This is a specific type of encoder known as an Analog-to-Digital Converter (ADC). ADCs are used in various applications where analog signals need to be processed, stored, or transported in digital form.

d. Performs arithmetic operations on multiple inputs - This is not typically a function of an encoder. Arithmetic operations on multiple inputs are usually performed by a processor or a dedicated arithmetic unit.

So, based on the options provided, the most accurate answer would be option c, "Converts data from analog to digital form", if we're talking about an ADC. However, if we're talking about a general encoder, option a, "Combines multiple inputs into one output" would be the most accurate.
