| Abstract: | With the study on the nonlinear distortion of network, this paper presents a new method to test the nonlinear distortion of network with FFT and PC audio card. By means of error analysis and practical examination, it has been proved that the method can achieve the goal which can test the nonlin-ear distortion of network with features of high precision, low cost, and being simple and fast. |
