Which of the given binary arithmetic operations would result in a sign overflow error? The values are assumed to be SHORT INT signed values. There could be more than one answers.  0b00011101 + 0b00001110 0b01000001 + 0b01000010 0b00000101 - 0b00000010 0b11111110 + 0b01000001   Assume a processor with a 500 MHz clock takes 500 clock cycles (ticks) for a polling operation. Determine the fraction of processor time for polling given that we want to poll the device at 50 Hz so as not miss any data. Write your answer as a fraction (not a percentage), as a real number. If the result is an integer, then add the .0 to the number to make it a real number. For example, write something like 0.025 or 5.01 or 2.0.

Assume a processor with a 500 MHz clock takes 500 clock cycles (ticks) for a polling operation. Determine the fraction of processor time for polling given that we want to poll the device at 50 Hz so as not miss any data.
Write your answer as a fraction (not a percentage), as a real number. If the result is an integer, then add the .0 to the number to make it a real number. For example, write something like 0.025 or 5.01 or 2.0.
