| Abstract(in English) | The time jitter generated in the analog/digital converter (AD/DA) causes errors during impulse response measurements. We carry out an experiment for studying the influence of time jitter on the accuracy of impulse response measurements. In the experimental system, time jitter is digitally generated. The system can control the distortion due to time jitter without special hardware. We use the system to consider the impact of the time jitter on two impulse response measurement methods : Time Stretched Pulse (TS P) and Maximum-length sequence (M-sequence). We find that TSP performance depends on the amplitude change in the TSP signal at each sample. The TSP method is shown to be more robust than the M-sequence method with regard to time jitter. We propose a method based on complex cepstrum analysis that can, in combination with either TSP or M-sequence, better resist the effects of time jitter. |
