Hi,
Jose's correct. Co-channel TV stations are accurately offset by a
fraction of the line frequency. Interestingly enough (and for this
reason) independent TV stations often have very accurate transmitter
frequencies, while potentially having quite poor (1e-6 or so) control of
the picture

Ah-ha!
Satellite broadcasters have poor stability - not necessarily so.
Many years ago (about 1978, actually) we were sending a signal from
Johannesburg to UK by satellite. In our control room, we could see both the
signal
As one who has worked in the pro digital audio field for years, I can
tell you that sub-100 ps jitter very definitely can be heard,
depending on its spectrum. Modern sigma-delta ADCs and DACs use
oversampling clocks of 12 to 50 MHz for sample rates of 44.1 kHz to
192 kHz at 24-bit resolution

It's also interesting when two list members disagree by so
many tens of dB, so I'm hoping David and PHK can settle
this for us.
I doubt it, at the end of the day, much of

Bruce,
You have been more precise than this in other posts. Can you put
some numbers behind the sigma delta DAC's sensitivity to jitter?
Twenty years ago, the process control community got all jittery
about the jitter in the

Just noting a few points made recently on this topic.
Do not confuse the Studio colour subcarrier frequency
(4.43 or 3.58 MHz) accuracy - or the digital equivalent
clock frequency - with the TV transmitters carrier
frequency
