Method for testing signal transmitting and receiving performance of DSP (digital signal processor)

Abstract

The invention discloses a method for testing signal transmitting and receiving performance of a DSP (digital signal processor). The method includes a process of testing signal transmitting performance of the DSP and a process or testing signal receiving performance of the DSP. The method has the advantages of higher reliability, convenience and low cost as compared with the prior art, and particularly has the advantages that reliability of signal transmitting and receiving performance of the DSP is guaranteed by the comprehensive testing method; testing can be carried out anytime and anywhere due to the fact that devices for testing are simple and convenient; cost is low; and when applied to a telephone switchboard system, the method can provide effective tracks for solving the problem of calling fault and facilitates quick positioning and problem solving.

Description

technical field

[0001] The invention belongs to the application field of communication technology, in particular to a method for testing the sending and receiving performance of DSP signals. Background technique

[0002] Digital Signal Processing (DSP) continues to develop and progress with the development of related industries, especially the communication industry, and DSP general-purpose chips for audio processing are widely used. In view of the basicity and importance of audio processing, especially digital signal transmission and reception in the field of communication, how to effectively test the performance of DSP digital signal transmission and reception to ensure the smooth call of the communication system has become particularly critical.

[0003] At present, the DSP digital signal transmission and reception test in the communication industry is often a simple call test with the help of the telephone exchange system. Such a test is one-sided and cannot guarantee th...
