HW #8: Explain how a 2x oversampling CD player works.
A CD player reads a dicrete set of data off a CD. In short, a CD player takes this data and sends it through a digitla to analog converter, then through a low pass filter, and finally is output through speakers. A simple diagram illustrates this below.
(Figure 1 to be inserted)
When an audio CD is recorded, the music has an infinite amount of data points and can be represented as a continuous function of time . Because a medium, such as a CD, has a finite amount of space, it will not be able to hold since it has an infinite number of points. Instead, the music is sampled at intervals to create a discrete function of time where is an integer and is the period.
