Smooth and continuous data is a characteristic of a(n) analog signal
binary signal
digital signal
pulse signal

Smooth and continuous data is one of the major features of an analog signal.

Analog signal isn't as accurate as the digital signal and it contains minimum

and maximum values which could be positive or negative.

Analog signal comprises of smooth and continuous data. This is explained

by one time-varying quantity representing another time-based variable.In

this type of signal , a variable is an analog of the other.

Analog signals examples include the following : Human voice, Thermometers, analog clocks etc

Explanation:

Continuous data is a characteristic of analog signals though been smooth is a subject of question. The smooth signal is after it's been processed. However a wave can still stay continuous defined by what we call duty circle.
