Equalisation for Archival Transfer: In the
Analogue or Digital Domain? S.W. Davies
See page 3: under "Disadvantages" [of equalisation in the
"There may be a bit penalty to allow for headroom in the
A/D conversion. For instance, taking the RIAA curve there
is a lift of nearly 20 dB at 20 kHz so that the transfer
level would have to be reduced by this amount which implies
the loss of 4 bits compared with analogue equalisation.
Low frequency boost could carry a 3 or 4 bit penalty."

Can you describe the mechanism by which the dynamic range is lost in
this process? Or can you point me to any relevant literature that
fully explains this?
Thanks in advance.
