Which of the following is not an example of an analog signal?

Explanation:
Analog signals represent a continuous range of values, changing smoothly as the measured quantity varies. A voltage that can sweep from 0 to 10 volts is a classic analog representation because it can take any value within that span. A 4-20 mA current loop also carries information as a continuously varying current, encoding different levels in a smooth, ongoing way. A pressure reading expressed as 3-15 psi similarly produces a value that can lie anywhere within that range, making it another analog signal. Digital 1/0, in contrast, uses distinct, discrete states—typically two levels, on or off. It does not vary continuously, which is why it is not an analog signal.
