VI for fft analysis for free vibration anlysis of beam.

[jyothiape]

I am doing my mtech project in free vibration analysis of beams. My PXI-1052 equipment gives the data on the timebased domain. I need to convert the time based amplitude values into frequency domain by fft analysis. I have made a VI. But it doesnt serve the purpose of taking the time and amplitude  values from the excel sheet and carryout fft analysis.

Can anyone help me outwith a VI for Labview which helps me to obtain my required results. I am new to labview.

I have attached my VI and excel sheet with this.

You mention reading from an Excel file, but you have no functions in your VI to do this. If you want to read from an Excel file I recommend looking into reading from an Excel file.
