FFT to covert time domain to frequency domain

2 次查看(过去 30 天)
I have excel file which consists of readings of time and corresponding amplitude of Vibration analysis. I have to do signal processing for Vibration analysis. First, I have to plot time domain graph and then convert it into frequency domain using FFT. Sample rate is 12000 and sample length is 8000. Please give me the code for above requirement.
