To all

I have searched in the doc (signal processing) but cannot any function doing the "half power" (frequency) band.

if I have a set of data (X,Y) and a known point (Xn,Yn), I want to know the 2 co-ordinates X1 & X2 [(X1,Y1) & (X2,Y2)]  so that

Y1=Y2 = Yn/sqrt(2).

Set up a simple "search" function but surely there must be something in mathcad!

Thanks

Can you post a worksheet with some example data?

See attached zip file. The idea is to see if later, once I have managed to "automatically" extract the value [f1-f2], I can find the variable (part of known equation) required to fit the data in the range of interest

You could easily include the data in the Mathcad-Sheet via Insert/Data/Table.

See attached.
