Voltage Gain Block
 National Instruments Corporation 1-29 Multisim Component Reference Guide
1.31 Voltage Gain Block
This component multiplies the input voltage by the gain and delivers it to the output. This
represents a voltage amplifier function with the gain factor, K, selectable with the Value tab of
the component’s properties screen. The voltage gain block is used in control systems and
analog computing applications.
In the example shown below, the input is a 0.707v RMS (2v peak to peak) sine wave and the
gain factor K is set at 5. The output then is K times the input.
(.707*5= 3.535v RMS or 10 v peak to peak)
Caution Using the default model, as in this example, sine wave inputs
may be any value.
B3 Denominator 3rd order coefficient 0 -
B2 Denominator 2nd order coefficient 0 -
B1 Denominator 1st order coefficient 0 -
