 National Instruments Corporation 1-31 Multisim Component Reference Guide
1.32 Voltage Differentiator
This component calculates the derivative of the input voltage (the transfer function, s) and
delivers it to the output. It is used in control systems and analog computing applications.
Differentiation may be described as a “rate of change” function and defines the slope of a
curve.
Rate of change = dV/dT
