1. What are two types of variables that can be used for values that exceed 256, and describe what is the difference between the variables, how to declare them and the memory allocated, and the numerical range for both.
2. Describe why designers often use a signal conditioning amplifier circuit prior to applying the signal to a microcontroller ADC.
3. An 8-bit DAC outputs a value of 9.961V when the input is 0xFF. What is the output when the input is 0x5A?
