Blurry bright waves against a dark blue background.
Gina was summarizing what she read to her friends and shared this image, calling it a digital signal. Is she correct in saying this? Explain your answer.

No — she’s not correct. The picture you describe (smooth, blurry bright waves on a dark background) looks like an analog waveform, not a digital signal.
Why:
- Analog signals vary continuously in amplitude and time (smooth curves, sinusoids, etc.). The “wavy” smooth shape and blurriness fit that description.
- Digital signals take on a limited set of discrete levels (often two levels for binary) and look like steps or pulses (square waves) when plotted versus time.
- “Blurry” could indicate noise or smoothing — again typical of continuous analog signals.
One important caveat: the image file itself is stored and shown on a digital device, so the picture is a digital representation of whatever waveform was recorded. But the waveform shape depicted — smooth, continuous waves — is characteristic of an analog signal.
