One of the most frustrating aspects of car audio is noise in the system. Unlike home audio systems, car audio systems have many sources of noise to deal with. Here's a few of the most common noises found in car stereo and how to fix or avoid them.
While the mean of a set of values minimizes the sum of squares of deviations and the median minimizes the average absolute deviation, the midrange minimizes the maximum deviation (defined as max | x i â m | {\displaystyle \max \left|x_{i}-m\right|} ): it is a solution to a variational problem.
A trimmed midrange is known as a midsummary â the n% trimmed midrange is the average of the n% and (100ân)% percentiles, and is more robust, having a breakdown point of n%. In the middle of these is the midhinge, which is the 25% midsummary.
