Video Fader
The Video Fader circuit provides a unique function. Here Ch B
is applied to the minus Z input in addition to the minus Y input.
In this way, the function in Figure 11 is generated. V
MIX
will
control the percentage of Ch A and Ch B that are mixed
together to produce a resulting video image or other signal.
The Balance equation looks like:
Which simplifies to:
When V
MIX
is 0V the equation becomes V
OUT
= Ch B and
Ch A is removed, conversely when V
MIX
is 5V the equation
becomes V
OUT
= Ch A eliminating Ch B. For V

5V the output is a blend of Ch A and Ch B.
Other Applications
As shown above, a function may contain several different
operators at the same time and use only one HA-2556.
Some other possible multi-operator functions are shown in
Figures 12, 13 and 14.
Of course the HA-2556 is also well suited to standard
multiplier applications such as Automatic Gain Control and
Voltage Controlled Amplifier.
Automatic Gain Control
Figure 15 shows the HA-2556 configured in an Automatic
Gain Control or AGC application. The HA-5127 low noise
amplifier provides the gain control signal to the X input. This
control signal sets the peak output voltage of the multiplier to
match the preset reference level. The feedback network
around the HA-5127 provides a response time adjustment.
High frequency changes in the peak are rejected as noise or
the desired signal to be transmitted. These signals do not
indicate a change in the average peak value and therefore
no gain adjustment is needed. Lower frequency changes in
the peak value are given a gain of -1 for feedback to the
control input. At DC the circuit is an integrator automatically
compensating for Offset and other constant error terms.
