Benjamin and Gannon, the first reference in Ashihara's paper, come to lower
figures for sinusoidal jitter with carefully selected frequencies relative to
the main signal, which is also sinusoidal. Their results reach down to the
single figure nanosecond range, and that can be regarded as the real limit of
audibility.
Are there any real audio systems with "sinusoidal jitter".
powerline ripple on a signal going into a threshold detector that drive
the sample clock would be a nice way to generate sinusoidal jitter.
I've got a nice example where 66MHz processor clock modulates a 49MHz
sample clock (well, it's not perfectly sinusoidal, but if you digitize a
clean sine wave, you get nice aliases of the modulation frequency).
I'd goes
that it would all be random. I can see where I could build a
system with that defect if I wanted to but are there any systems on
the market like this?
