Question $1$

A particular flapping$-$wing micro air vehicle contains an eight$-$bit shaft encoder that can return

a value in the range of $-..$ radians. This encoder position is the angle, in radians, that

the wing is rotated forward $($negative values$)$ or backward $($positive values$)$ of a neutral "fully

flat" position.

What is the dynamic range of this sensor in decibels $($approximately$)$
