Predefined Time Functions
Predefined time functions have a quality determined behavior for which certain parameters
can be defined. Predefined time functions are: Sine, Pulse, Triangular and Trapezoidal wave
as well Needle pulses, Arc tangent and the Controlled oscillator.
In the property dialog, the frequency, period, initial delay, amplitude, phase, periodicity and
offset can be modified. In addition, for all predefined time functions there is a preview mode,
which displays the time functions for the defined points in a graphic window.
Changing Period
You can change the period independent of frequency. The period reduces or lengthens the signal
depending on the period of the corresponding period (1/frequency).
Period = 1/f
the signal is depicted exactly
User-Defined Time Functions
Period < 1/f
the signal is shortened
Period > 1/f
the signal is lengthened
In addition to the predefined time functions, you can define your own time functions. The 2D
Lookup Table create time function data pairs which are saved in an external file or in the simulation
sheet.
The parameters period, initial delay, phase and periodicity can also be changed in this dialog.
For all user-defined time functions there is a preview mode, which graphically displays the
created time function.
