Thank you for your reply. I did do a search on here to check but didn't find an answer.

I have a document which consists of a number of Microsoft Equation Editor objects. I need to copy these into MathCAD. Is it possible to do this so that the equations can be used within MathCAD? If not, is there some kind of import facility? Your advice would be much appreciated! Clive [infinity]

Thank you - your answer provides the clarification I needed!

Hi, I'm writing a software application which applies Fourier Synthesis to some electrical frequency-domain data (i.e. harmonics comprising a harmonic number, amplitude and phase for each harmonic). My question relates to the resultant periodic waveform - how many plot points (i.e. time values)...

IRStuff, So far I have only done a Fourier Synthesis using the equation at the top of this post. What I'm trying to find out is how to do Fourier Analysis with the data I currently have.

The magnitude/phase data describe various electrical power system elements. So for a busbar element the magnitude is the voltage (in volts) and for other elements it is the current (in amps). It's in polar form. Does this help describe the data (I'm not really sure what else I can say about it!)?

At the moment, I pass in real values (i.e. magnitudes and phases) into the above equation which produces real values as output to use in a time plot. My data is not in digital form so what technique is best to go with? Basically, I'm a bit confused with all the terminology i.e. Discrete Fourier...

I'm a software engineer working on a project to plot harmonic waveforms from source data. I do this using a Fourier approximation - taking harmonic numbers, magnitudes and phases as input, and deriving magnitudes to be plotted against time. I use the following equation: f(t) = sigma (from n =1...
