Aliasing Explained in Simple Terms | DSP Basics

Have you ever seen a rotating wheel appear to spin backward in a video?
That’s not magic—it's called aliasing.

In this video, we break down aliasing in the simplest way possible using real DSP examples.

What you’ll learn:
• What is aliasing in signal processing
• Why it happens when sampling rate is too low
• How a 6 kHz signal becomes a fake 2 kHz tone
• Samples per cycle concept (1.33 samples problem)
• Real-world example (audio distortion & video illusion)

Aliasing occurs when your sampling rate violates the rules of the Nyquist Theorem—causing high-frequency signals to appear as completely different lower frequencies.

Key takeaway:
If your system captures less than 2 samples per cycle, your signal will be misinterpreted.
