Let denote the component of the impulse response arising from
the th pole of the system. Then the energy associated with that pole
is
All other factors being equal, if the decay time of the mode is
shortened by half, it follows that the total energy contributed by
that mode to the impulse response is also reduced by half. To
compensate for this effect, Jot introduced a tonal correction
filter to be placed in series with the FDN, as shown in
Fig. 2.6.
In the case of the first-order delay-line filters discussed in
§2.6.5, good tonal correction is given by the following one-zero filter:
where
and is defined in Eq. (2.4).
