What type of signal is continuous, varying from a minimum to a maximum value?

Explanation:
Continuous variation from a minimum to a maximum value describes an analog signal. An analog signal changes smoothly over time and can take any value within its range, so its waveform isn’t stepped. Digital signals, by contrast, use discrete levels (often just two) and change in steps. Discrete signals are defined only at specific sampling instants, not all the time, and pulse signals are short bursts rather than a continuously varying waveform.
