The statement is false. Analog signals can have more than two states.

An analog signal is a continuous signal that can take on any value within a specific range. Unlike digital signals, which have only two discrete states (0 and 1), analog signals have an infinite number of possible states within their range.

For example, consider a simple voltage signal. In digital electronics, a signal might be represented by either 0V (low) or 5V (high). This is a digital signal with only two states. However, in analog electronics, the voltage signal can take on any value between 0V and 5V, including values like 2.3V, 3.7V, or any other value within that range.

Analog signals are used in various applications where continuous and precise representations of data are required, such as in audio signals, temperature readings, and voltage measurements. They are essential in many fields, including communications, control systems, and instrumentation.
