Compression and expansion process for delta modulation communication especially for mobile phone conferencing converts input signal into a delta value evaluates and adjusts output
Compression and expansion process for a delta modulation communications device (1) comprises converting an input signal into a delta-modulated value (13-15) in a sender (2), passing it to a receiver (3), finding a compression/expansion value from a held value passing to a sender and adjusting the value. An independent claim is also included for a device for the above process.
