Hi,

I am new to Mathcad, and I am using Mathcad prime 3.0. I need to plot the phase of my transfer function and am lost where to start. Here is what I have. Phase 1.PNG Phase 2.PNG Phase 3.PNG Phase 4.PNG

Any help would be greatly appreciated! Thanks.

I was not aware that "arg" and even "Re" and "Im" are considered "Premium" features.

But you can create your own function using "atan2" and the complex conjugate, as they are not premium:

"was not aware that "arg" and even "Re" and "Im" are considered "Premium" features."

Ah, I reported that a year ago Re: Plotting/calculating transfer functions.

Thanks for the tip on arg().

I't usually better to attach the Prime file (along with any pictures). To attach the Prime file use the Action => edit entry ( lower left corner of your post) and then you will see an Attachment option at the lower left side of the edit window.

So, I see a lot of definitions and functions, but which is the transfer function that you want to plot the phase of?

I won't retype all your expression, so here is just a small example including grid lines.
