12.2.2 Postprocessing with Display Elements
SIMPLORER 6.0 — Manual 381
The Display Postprocessing Elements provide online analysis functions. The DAY Post Processor,
in contrast, can only use simulation results contained in files.
Operations with Output Channels
FFT Element
You cannot use results of the postprocessing elements in the simulation model. The display
channels are used only to determine the graphical presentation.
SIMPLORER offers several mathematical functions to perform signal post processing online
on the sheet. Connect Views can display calculated values via a connection.
The outputs of the Simulation channels are connected with operators, and the output of the
operator is connected in turn with a display element (through Connect View).
See also “Outputs in Connect View Elements” on page 371.
The following operations are possible:
• For one simulation channel
Derivative
Integration
FFT
Negation
Reciprocal value
Offset
Scale
Smooth
• For two simulation channels
Multiplication
Summation
Channel Calculator
The FFT Element carries out an online FFT of an input signal connect to the pin and provides
the result at the five output pins. In the sense of SIMPLORER Display Elements the FFT Element
represents a connect element. The calculation is sine-based that means, a cosine signal
would have a phase shift of π/2.
Inputs
I1: Input Signal, I2: External Time Channel
Outputs
Modulus and Phase
O1: Frequency, O2: Input Signal, O3: PHI [rad], O4: PHI [deg], O5: Amplitude [%]
Real and imaginary part
O1: Frequency, O2: Input Signal, O3: Imaginary Part
Base Channel
The choice «Time Channel» uses the simulation time. If you want to use a other channel, you
have to select «External» and connect a simulator channel to input pin 2.
