Unformatted text preview: 3. A 4-bit adder subtracter (A±B) as designed in class is presented the operands A=1001 and B=0011. The signal a / s = 1 . What calculations are performed assuming A and B are (i) un-signed and (ii) signed. What are the results in each case, and how do you know? 4. A temperature measurement module yields the following temperature stored in IEEE single precision Foating point format: 0x42948000. What value is encoded. 5.
