Basic Compandor System
The above basic compressor and expandor can be applied to
systems such as tape/disc noise reduction, digital audio, bucket
brigade delay lines. Additional system design techniques such as
bandlimiting, band splitting, pre-emphasis, de-emphasis and
equalization are easy to incorporate. The IC is a versatile functional
block to achieve a high performance audio system. Figure 9 shows
the system level diagram for reference.
