Man, I'm glad they turned that into db & % at the end, I was just about all P'd out **broken link removed**
Will have a go on sim tomorrow as late now but I stuck at it until it made sense **broken link removed**
Sim looks ace, what is a FET then I know it's being used as a switch but what is one, never heard of it **broken link removed**
So let me get this right in my head, the square wave is referred to as half a cycle because it has nothing below gnd, so it's only one side of a sinewave or 180degrees or 1 radian
So looking over sim properly, it looks like a intermittent relay for uses that KISS gave above
