How do I change the sampling rate of my design in SigmaStudio?

If you have a new design (empty schematic), then you just need to set the sampling rate in the drop-down box at the top of the SigmaStudio window. Then, every block placed in the design after that has been set will use that sample rate for its calculations. If you have already placed blocks in your design, you still need to first set the drop-down box for any future blocks that may be added. Also, you will need to right-click on all input blocks (inputs, tone generators, etc.), select "Set Sampling rate," and enter the appropriate frequency.
