Question

Suppose you are designing a tool to determine the amount of charge remaining in a 15V battery. In order to do this you will need to read the voltage of the battery, which could range from 0V to 15V depending on its current level of charge. When selecting an analog-to-digital converter (ADC or A2D in the book) for this tool, how many bits would the ADC need output in order to represent each possible integer voltage? Hint: How many whole voltages do you need to represent and how many bits would this require? 0 2 4 0 5 06 12 None of the above

Explanation / Answer

Answer) 4

Explanation:- The range of voltage is 0V to 15V , which can have 16 different values like 0,1,2 .... 15. To represent these 15 values in binary, 4 bits will be sufficient (2^4 - 1 = 15)
