Dear All, Changing only FFT size of the freq sink block during simulation drops signal power drastically, screenshots are given in the attachments. I am providing the pulse burst from the vector source as 6144 points (6 ones and the rest of the points are zero). Since FFT sink blocks show the average power of the points on freq domain, increasing FFT size would increase the number of zeros in the buffer so power is reduced.
What do you think about this approach, is it ok? and there are fluctuations in the 32k example, that's why it is thicker than 4k plot, what is the reason for this? Moreover, no unit is written in vector or signal sources amplitude sections. Are units assumed as volts?
