Question

the apple iphone includes a settings menu where you can toggle various accessibility options on or off: mono audio phone noise cancellation hearing aid compatibility what is the minimum number of bits that can represent those 3 options?

Explanation:

Step1: Recall bit - representation formula

The number of values \(n\) that can be represented with \(k\) bits is given by \(n = 2^k\). We need to find the smallest non - negative integer \(k\) such that \(2^k\geq3\).

Step2: Test values of \(k\)

If \(k = 1\), then \(2^1=2\lt3\). If \(k = 2\), then \(2^2 = 4\geq3\).

Answer:

2
