Default New page on Squares waves and amplifier performance

Well, obviously, in the days I was talking about, digital recording was
still in the domain of the pro, and tended to sound very furry by comparison
to good analogue.

However I remember having a bit of a heated argument about the realism or
otherwise with some test luminary at a Heathrow Hotel show back then.
Pointing out that the dc coupled amp was a complete waste of time as
speakers could not really do constant air pressure unless you lived inside
an infinite baffle enclosure in any case.
I agree crossovers by their design had phase shift, after all they are
basically fillters.

I then got into some heated discussion about doppler with a lowther
enthusiast..

We used to use squarewaves for the following.
To show how bad tape machines were...
To show the tone control effects

However, you need to look at the harmonics on a true square wave, which
of course cannot actually exist.


**If you REALLY want to laugh, look at a 7kHz square wave from a CD player
(even 5kHz is barely passable from most CD players). A good R-R or high
end vinyl playback can do a MUCH better job.
