are subject to change.
2)
Ail voltages
are
rms
(root-mean-square).
3)
0
dBv
is
defined as 0.775
V
regardless of
load Impedance. Subtract
2.2
from the dBv
figure to
convert to dBV
(i.e.,
referred
to
1 V).
When
the load impedance
is 600
ohms,
this
particular dBv
is also Known
as "dBm."
4)
Noise figures
are
for
20
Hz-20
KHz.
5)
Attack time is
the
time required to restore
the
signal
to
654b of the input level
after It
has
gone above the
OverEasy
threshold;
release time is the time
required
for
the
signal
to be
reduced to 654b
of
Its final gated
level.
