Lecture 3: Sampling, Aliasing, Antialiasing (86)

I'm having trouble understanding where exactly the "high frequency masquerading as a low frequency" phenomena is occurring here- if you go from left to right, you're still seeing a step function right? it's just in different spots?


I am having the same problem. How can we interpret high frequencies and low frequencies from images? How does this example demonstrate a high frequency being aliased?
