We ran into several problems, namely manipulating the input voltage into a 12 bit number that could be output. + We rearranged the given formula and accounted for outputting a 16 bit number as a 12 bit number. We also had to make sure that the types were correct when manipulating the voltage and doing + calculations. + +Analysis: + Resistors) + Our resistors were all very close to their ideal values. They weren't perfect because they are physical systems and have a built in error of around 1% due to + manufacturing defects and temperature variations. They all seemed to be operating within that range. + + Voltage) + The main error for measuring voltage came from our output being a quantized version of an analog output. It can never be perfect. If we get a reading that is on the edge of + a voltage cutoff, it will be slightly off. That being said, all of our measurments were very close. + + Current) + Current was where we had our largest variations, this was moslty due to our multimeter having a 0.02 mA variance. Even when disconnected the multimeter read 0.02 mA. The other variances + were from differences in resistor values and voltage, which impact the current. \ No newline at end of file
