Misleading Measurements


Recommended Posts

It might help to not spend too much effort understandIng AES17-1998 given the Forward of AES17-2015 states:

This document substantially revises and updates AES17-1998

and the Forward of AES17-2020 states:

This document clarifies the definition of levels, the units FS and dBFS.

I don't have the new document (nearly twice as long as the 1998 standard), but perhaps all is made clear!?

Thanks.  I think I am beginning to see it. For 2 vrms (sine wave) which = 2.8 v peak, if we set that to  0 dB FS, then for a square wave, the rms = peak = 2.8 v.  We can never have a peak higher than 2.8v.  However, rms can vary from 2.8 v and downwards for different waveforms. Is this correct?  And do we zero the rms meter? (It would seem that we would need to zero it at 2.8 -- this would mean that both peak meter and rms meter get zeroed at 2.8).

 

 

 

Yep this is pretty much it 😀

 

Im not quite clear on the "zeroing" (bit been a long day my fault).

 

Found this, might help someone
