in the official db drag cds they have sine waves and clipped waves. i was wondering why that is. How would a clipped signal be a good thing and how does it increase SPL.

For some people/amps a clipped signal will score a bit higher

cliupping kinda gives the sound wave a different shapef wave.. in other words it's like a square wave.. and in ALOT of spl vehicles this works as louder

Ice, do you understand what an amplifier is doing during each cycle of a wave. I'm talking about the power output.

If you understand that then you should be able to figure out with a clipped wave is SOMETIMES louder.

Look at the time domain in a graph of a clipped wave vs clean and it should be apparent why a clipped wave contains twice the power at the same applitude....

A completly clipped wave will have a 2db gain at the fundamental and 1db is put into odd harmonics...

In otherwords if you are an SPLer and your amp still has current on hand while you are burping you can gain output by overdriving the inputs and clipping the signal...

On the otherhand you would be better off if you were getting all that current in a clean signal...

If you are clipping because the amp is out of current you can loose output at your fundamental....
