If a digital thermometer needed a resolution of at least 01

If a digital thermometer needed a resolution of at least 0.1 to accurately measure human temperatures between 95 degree and 108 degree, how many bit sensor is required?

Solution

Given that

Initial temperature T1 = 95

Final temperature T2 = 108

Number of bits required = [T2 - T1] ÷ 0.1

= [108 - 95] ÷ 0.1

= 130
