Experiment prompted by forum discussion. This compares a sine wave with a semi-circular wave. If you zoom in on the second waveform using an editor you can see the wave shape is semi-circular (you obviously need to scale the time axis exactly).
Description:
3 secs of sine wave (f = 440Hz) followed by 3 seconds of semi-circular wave (f = 440Hz).
