[mathcad] DSP method

Author: Mark Smith Posted: Wed, 11 Jan 2006 17:26:03 -0000

I have 2 digitised signals (A2D sampled) which are very similar in shape but
differ by a fixed time difference, can anyone suggest methods which will
allow me to calculate what the time difference is?
I have the feeling that if i can somehow use all the data I should get a
much more accurate value than say just comparing a zero crossing of the 2
traces which I think will be far more susceptable to noise in the signal.

Thanks in advance
mark

A huge thanks to all with their suggestion and at Ted's request attached are
some generated data files with noise added which are the sort of thing I'll
expect to get from the real world.

Product Reviews

"Our work ranges from complex medical imaging research to large-scale mapping and diagrams and we need a tool that is able to handle anything we investigate. With Mathcad, we are able to manipulate and analyse our data quickly while at the same time documenting our work, for sharing and publication. We also use it for pilot studies conducted in support of research grant applications. It is an end-to-end tool for research and development."
Dr. Kenneth Castleman, President of Advanced Digital Imaging Research (ADIR), Houston, Texas

"Mathcad is an integral product for my work... With Mathcad, itís easy to disseminate design calculations because the documents look like real math. Thereís very little I canít do in Mathcad. The main benefits come from the format, which resemble a typed set of calculations. These programs are easier to develop by engineers and easier for others to follow and review since the logic is expressed in a familiar manner. The format is what places Mathcad head and shoulders above other programs of a similar function."
Andre Pavlov, Structural Engineer, Florida Department of Transportation
