I have two questions -
A)
I want to create a frequency banded input of specified band range in Simulink. Which is the most feasible option? a) Create a Band limited white noise and then filter it using bandpass filter..b) use many Sin blocks and then add them together c) use chirp block and then filter it for the specified range
(both continuous and discrete)

B) I need to take its fourier transform. I tried different sinks available like PSD, Spectrum analyzer, spectrum scope and magnitude fft. But there seems to be a small problem. I need a simple graph of amplitude vs frequency of the whole range of the frequency. Which I am unable to get. Some blocks do windowing some blocks dont show the complete range while some block show PSD. If you could tell me what exactly I need to do, it would be of great help

Thanking in advance
