I have a 3 rad/s sine wave that I am sampling every 2 seconds.

The slow sampling has created an alias of -0.14 rad/s.

I have plotted this over the top of the original continuous time signal, please see attachment.

My problem is that I only want to plot the first period of the discrete signal, i.e. end at 44.88 seconds, but I want to plot the original CT signal for the full 60 seconds.

I'm going around in circles and getting some strange results. Hopefully somebody out there can shed some light.

Cheers

Steve
