Which instrument is commonly used to display waveform signals?

• A. Multimeter
• B. Oscilloscope
• C. Signal Generator
• D. Amperemeter

Answer: (B)

The oscilloscope is the instrument that is commonly used to display waveform signals because it visually represents voltage signals over time, allowing users to analyze the shape, frequency, amplitude, and other characteristics of the waveform. This capability is crucial for observing signal behavior in various applications, such as troubleshooting electronic circuits and analyzing communications signals. While a multimeter is used to measure electrical properties like voltage, current, and resistance, it does not provide a graphical representation of waveforms. Similarly, a signal generator produces waveform signals but does not display them; its primary function is to create specific waveforms for testing purposes. An amperemeter measures the current flowing through a circuit, but like the multimeter, it does not visualize waveforms. The oscilloscope is specifically designed for waveform analysis, making it the correct choice in this context.
