What term describes the representation of an analogue signal using binary data?

The term that describes the representation of an analogue signal using binary data is "digital signal." In digital signal processing, analogue signals, which are continuous in nature, are converted into a binary format that can be processed by digital systems. This conversion typically involves methods like sampling and quantization.

A digital signal consists of discrete values (0s and 1s) that represent the analogue signal’s variations, allowing for improved storage, transmission, and processing efficiency. Digital signals tend to be more robust against noise and interference compared to analogue signals, making them preferable for many modern applications in computing and telecommunications.

The other terms provided do not accurately describe this concept; for example, an analogue signal refers to the original, continuous signal itself, while hybrid and linear signals do not specifically pertain to the representation of analogue signals in binary form.
