I am very new to simulink and I'm having a terrible problem I can't seem to figure out. I want to use the spectrum scope block to calculate and display the FFT of an impulse. Every time I try this, the spectrum scope display goes blank; just a couple horizontal lines around -3233. I've tried decreasing the sample time and increasing the run time but I still can't get anything to work. If anyone can give me any pointers you'd be a lifesaver.
