Question:
Let X denote the voltage at the output of a microphone, and suppose that X has a uniform distribution on the interval from to 1.
The voltage is processed by a “hard limiter”
with cutoff values and .5, so the limiter output is a random variable Y related to X by if if
, and if .
a. What is ?
b. Obtain the cumulative distribution function of Y and graph it.
