Abstract: A system for testing a bus is described. The system utilizes a tester which includes decompression circuitry to decompress digitized ADPCM signals transferred over a bus, data in the decompressed ADPCM signal is used to determine whether data losses or transmission errors are occurring on the bus. When such errors occur, the tester transmits a warning signal.
