Converting Time vs Voltage to Frequency vs Voltage
Show older comments
I have an excel sheet containing the time in first column and voltage in second column for a filter.
I would like to plot this data in the form of Frequency vs Voltage ie the voltage given in the excel sheet.
How can I do this in MatLab?

Use the xlsread function to import your data into your MATLAB workspace.
See the documentation for fft (link), specifically the code between the first (top) two plot figures.
