How can I cast a signal from an unsigned to a signed in DSP builder in simulink? 

 

I have an unsigned inputs, which I difference (with positive or negative results. How can I either cast both of these inputs to a signed value easily without doing silly bus concatenations so I can input them into the subtractor? 

 

Thanks for any help.

Use an AltBus block from the IO & Bus library in Altera DSP Builder Blockset.
