Frequency and Amplitude
It can be a real brain twister trying to remember the difference between frequency and amplitude.
Here's a quick breakdown.
Changes how frequently there are changes. Higher frequency, more wiggles. Lower frequency, less wiggles.
Changes the size of the wiggles. Higher amplitude, higher wiggles. Lower amplitude, lower wiggles.
All of these examples are using a
sin wave. But this it true also of
noise, and other kinds of wiggling that we do with numbers!
