Evaluate Boolean with Numeric Input

Evaluate Boolean with Numeric Input

‎02-05-2010 11:18 AM

Studying for CLAD exam and I'm stumped by an example using numeric inputs for the "or", "and", and "xor" boolean functions.  How do you logically trace dataflow in these instances?

 

Thanks.

Maybe it would help you understand bitwise operations if you selected binary display. (10 OR 00 = 10)

If you wired it up in LabVIEW, you are probably getting some negative numbers, right?

 

😄

 

0x00000010  = 2

0x00000000  = 0

 

XOR

 

0x00000010  = 2

 

XOR.not

 

0x11111101 =  253 (U8) = -3 (I8)

 

You'll also get -3 (I32).

 

The minus sign gets people confused...  😉
