ML145554, PCM Codec-Filter

A codec *filter is used for digitizing and reconstructing thehuman voice.

These devices were developed primarily for the telephone network to facilitate voice switching and transmission.

Once the voice is digitized, it may be switched by digital switching methods or transmitted long distance

These devices perform the voice digitization and reconstruction as well as the band limiting and smoothing required for PCM systems.

They are designed to operate in both synchronous and asynchronous applications and contain an on chip precision voltage
