no.. i m sure.. its in frequency domain(frequency vs head)... in time domain, i have different diagram(time vs head), not mentioned in this paper.

Thanks... but fig. 2 is in frequency domain.they pick all peak values of this type diagrams and they invert them.. then they apply Fourier transform... resultant diagram 3 and 4 is in frequency domain.

If u can open directly then.. this is link.. http://scitation.aip.org/getabs/servlet/GetabsServlet?prog=normal&id=JHEND8000134000005000658000001&idtype=cvips&gifs=yes Title: Discrete Blockage Detection in Pipelines Using the Frequency Response Diagram: Numerical Study Authors: Pedro J. Lee1...

no.. can u give me ur email Id. I will send u a journal paper where on page no.4, this is explained. It will be more convenient... FRD is frequency response diagram. they select frequencies corresponding to peak values of FRD. then they apply Fourier transform. results are shown in diagram 3...

no.. i don't have software... i m searching on net but i get FFT and IFFT... means if i apply on frequency domain... result in time domain.. and vice versa. but I need result in frequency domain...

I have a frequency response diagram(frequency vs head) of discrete values. I have to perform Fourier analysis on these discrete values. The resultant frequency and head should be in FREQUENCY DOMAIN. how I can do this... by using FFT or any other ... using Nyquist frequency... please tell me...
