re-sample in a rectangular coordinate system from polar

[Mathew]

Suppose we take the red point on the polar grid. When i convert it to Re & Im parts i get a number in rectangular grid, but this point is not actually present in the rectangular grid shown on right. This polar point was found by interpolating some points. How can i find a point in rectangulr grid then?

thanks

Is this a homework assignment?

[Mathew]

Its a part of my prj wrk...any idea? I have to mapp the points in polar to rectangular.

There are some primitives in LabVIEW that deal with polar data-type conversion. Search the palettes.

Hello Ton,

Perhaps a primer in polar conversions: http://www.mathsisfun.com/polar-cartesian-coordinates.html

Maybe, x = r × cos( θ ) and y = r × sin( θ ) (from that site)

With regards to Re&Im, this concept is more or less a tool people use to think about sinusoidal stuff. Don't think you need it for this proj (i.e your Re{} is just 'x', and your Im{} is just 'y'). Let me know if you have any more questions and best of luck.
