[comp.dcom.telecom] Anyone Know of Any Chipsets For Mu-Law Digitation.

Hi,

I am thinking about designing/building a seven second delay for our
campus radio station.  I plan to run the phone line through an A/D
converter store the bits in RAM and read "old" bits back out through a
D/A converter.

I've been told that several manufacturers make chip sets to do mu-law
conversion.  I would be appreciative for any leads as to
manufacturer/chip numbers and any companies that would sell them in
single unit quantitys.


Thank you,

The IC Master lists A LOT of mu-law chips of various kinds.  Don't
suppose a simple digital delay line would much good once you had the
signal in digital, would it?  NEC makes several kinds of neat delays
for various applications.
