Question

An analog voltage is in the range 0V to 5V. If it can be measured with an accuracy of +/- 50mV, at most how many bits of information does it convey/represent?

Answer 1

the correct value is 7 bits that required to represent.

Step-by-step explanation:

Given data:

Voltage range is 0v to 5 v

Accuracy \pm 50 mV = 0.05 V

Meaning of 0.05 accuracy is 50 parts in 5000

so ratio can be written in the form of 1 in 100

so for representing 100 value 7 bits of information is required because 6 bits can represent 64 value only.

hence the correct value is 7 bits
