What
is
the
function
of
IC-7
of
the
MD-44
board?
Separate
chroma
from
composite
video
What
is
the
function
of
IC-8
of
the
MD-44
board?
Edge
compensation
Briefly
explain
how
luminance
is
separated
from
composite
video.
1H
delayed
composite
is
input
to
IC-12
Pin
3
through
RV-10.
Chroma
separated
by
the
correlators,
which
180°
outphase
with
the
1H
delay
composite,
cancels
chroma
components
in
the
composite
video
at
Pin
3,
IC-12.
Remnant
chroma
which
is
not
cancelled
is
inverted
and
removed
by
the
circuit
around
IC-11.
This
remnant
chroma
is
cancelled
at
the
mixing
amp
of
Q-36
which
outputs
separated
luminance.
How
is
AGC
detected?
By
sync.
level
What
RV
is
in
series
with
RV-23,
FM
Deviation
and
what
is
it
called?
RV-2
video
level
Briefly
explain
the
function
of
RV's
15,
16,
and
17
of
the
MD-44
board?
They
are
for
white
clip
and
dark
clip
and
are
used
to
limit
the
signal
applied
to
the
F.M.
modulator
to
prevent
over
modulation.
Briefly
explain
feedback
pre-emphasis.
This
feeds
back
signals
clipped
by
white
clip
and
dark
clip
back
to
the
main
signal
to
improve
High
Frequency
response.
What
is
the
function
of
IC-202
of
the
MD-44
board?
SP/CONV
mode
switch;
SP
and
conventional
have
different
filtering
characteristics
because
of
differences
in
frequency.
