Question
Please help with the 6 T/F questions and with the integer type questions. Thanks!
1. T/F: In signed 1’s complement representation, there is only one representation for zero.
2. T/F: To perform A – B, i.e., to subtract B from A, where A and B are two 32-bit integers in signed 2’s complement form, feed A and the bit by bit complement of B to a 32-bit full adder circuit as two inputs and set the Carry In for the least significant bit as 1.
3. T/F: In IEEE 754 single precision representation for floating point numbers, 7F800000 represents positive infinity.
4. T/F: Unicode has sufficient number of code points to represent all characters in all spoken languages of the world.
5. T/F: Any combinational logic circuit of interest can be built using only XOR gates.
6. T/F: CMOS technology uses less power than TTL technology and hence is preferred for portable devices.
