d) Damped Oscillation

Overview
An oscillation waveform where the oscillation attenuates in the exponential fall. An oscillation
waveform where the oscillation increases in the exponential rise can also be created.
Application examples
• Simulates a pulse response waveform accompanying an oscillation.

Meaning of each parameter
The example shows the case where the amplitude range is ±FS.
DampTC is positive DampTC is negative
•Oscillation frequency (OscFreq)
Variable range: 0.01 to 50.00 times fundamental frequency
•Damped oscillation time constant (DampTC)
The oscillation exponentially attenuates by this time constant when positive.
The oscillation exponentially increases by this time constant when negative.
Variable range: -100.00% to 100.00% of basic cycle
The peak value is fixed at +FS when the damped oscillation time constant is positive.
The oscillation is ± FS over infinite time when the damped oscillation time constant is negative.

Waveform examples
The polarity and amplitude range are all Normal, ±FS.
