Question 187

A signal processing algorithm converts an input voltage vvv into a compressed metric M(v)M(v)M(v) using the formula:

M(v)=ev/4+10 M(v) = e^{v/4} + 10 M(v)=ev/4+10

for v∈Rv \in \mathbb{R}v∈R.

Identify the expression for the inverse function M−1(x)M^{-1}(x)M−1(x).

Tick (✓\checkmark✓) one box.

□M−1(x)=4ln⁡(x)−10\square \quad M^{-1}(x) = 4\ln(x) - 10□M−1(x)=4ln(x)−10

□M−1(x)=1ex/4+10\square \quad M^{-1}(x) = \frac{1}{e^{x/4} + 10}□M−1(x)=ex/4+101​

□M−1(x)=4ln⁡(x−10)\square \quad M^{-1}(x) = 4\ln(x - 10)□M−1(x)=4ln(x−10)

□M−1(x)=ln⁡(x−10)+4\square \quad M^{-1}(x) = \ln(x - 10) + 4□M−1(x)=ln(x−10)+4
