        Hello,

        I'm looking for material about digitally implemented 
        compressor/expandor. Could anybody help me?

        At  cellular radio, dynamics of the signal is compressed 2:1 before
        sending  it  to  radio,  and  after  received  from  radio signal is
        expanded  1:2.  Nowadays we have analog implementation, but I'm
        making studies to change implementation suitable for TMS320C16.
