Depending upon whether one desires recording one side (simplex) or both sides (duplex) of a
conversation, the various paths will also be switched through to the low pass filter (for antialiasing)
and into the storage array. Later, the cell phone owner can play back the messages from the array.
When this happens, the Array Output MUX is connected to the volume control, through the Output
MUX, to the Speaker Amplifier. For applications other than a cell phone, the audio paths can be
switched into many different and flexible configurations. Some examples follow.
