These sample tones are audible with good loudspeakers or headphones, but many computer speakers will not reproduce them at all: a 100 Hz tone, (12 kb wav file) and a 10,000 Hz tone (44 kb wav file). Yesterday I did a test using the very accurate signal generator built into my CLIO system.
Blur Busters UFO Motion Tests with ghosting test, 30fps vs 60fps, 120hz vs 144hz vs 240hz, PWM test, motion blur test, judder test, benchmarks, and more. If using a 120Hz monitor, then 120fps is automatically added to this test (30fps vs 60fps vs 120fps) in supported browsers.

Consider data sampled at 1000 Hz. Start by forming a time axis for our data, running from t=0 until t=.25 in steps of 1 millisecond. Then form a signal, x, containing sine waves at 50 Hz and 120 Hz.
