Realization of PCM Decoding on Noise Data Compressor Testing Panel

In order to enhance the precision of data, collect data for processing and treatment, adapt digital technology and rapid development of large scale integrated technology, this paper proposes the coded modulation way of PCM （Pulse Code Modulation）. The testing platform of noise data compressor is used for coordinating the data compression installment to carry on the receiving of signal source, supply of power source, data＇s receiving and dispatching after compression as well as the correspondence with superior machine. The platform carries on the data and the order transmission through USB connection module and the computer, when the testing platform receives the reading order from computer, it takes over the compressed PCM code stream through the data receiving and dispatching module. This paper mainly decodes the PCM code downloading by noise data compressor in real-time, carries on the test through the superior machine readout, completes the function confirmation to the system.
