I am changing the fundamental frequency and the maximum harmonic value and the dc offset is coming different every time. how do I set the accurate parameters?
Do you make AC or Transient analysis. Transient is only meaningful for a starting portion of your waveform(e.g., from 0 to pi/2 of a sine wave
The DC component of a transient depends on how long it is and how long the data is. It is the mean value of all the data.
A transient response only lasts for a short while. A sine wave goes on for ever, which one are you analysing?
Dear Shivansh Awasthi ,
Please the display the waveform of the time domain. and then display the the FFT which you get. In this way one can put a specific reply.
The DC component is the average value of the waveform.
It will be seen as a discrete value at the zero frequency.
Best wishes
