摘要
格雷互補序列對具有非週期性自相關函數和為脈衝函數的特性，若使用於非時變線性(LTI)系統的輸入，則可從輸出計算出脈衝響應。本論文使用一階低通濾波器，進行電路模擬測試，並透過MATLAB分析模擬結果，驗證格雷互補對是可應用於類比電路的測試。 因m序列的自相關函數近似於脈衝函數，故也將其應用於一階低通濾波器的電路脈衝響應估測。由模擬測試結果得知，互補序列對比m序列更適合於電路量測。 本論文也對既有文獻 [AS92b] 量測結果進行探討，發現其測試結果並未出現一階電路的指數衰減脈衝響應型態。可能原因為取樣間隔太大，而且使用的PRBS序列自相關函數不佳，不近似脈衝響應。
並列摘要
Golay complementary pair have the property that the sum of aperiodic auto-correlation functions is an impulse function. If it was used in input of LTI, we can calculate an impulse response from LTT’s output. In this thesis, we used 1st-order low pass filter to execute the testing of simulating electrical circuit and use MATLAB to analysis the getting result that we can proof Golay complementary pair can be used for analog circuit testing. Because the auto-correlation function of m sequence is like the impulse function, it can be used to estimate an impulse response of electrical circuit in 1st-order low pass filter. From the testing result, we know the Golay complementary pair is better than m sequence in surveying electrical circuit. The thesis is also aim at the testing result of literature [AS92b] to do the research; we find the testing result didn’t have the type of exponential decay impulse response of 1st-order electrical circuit. It maybe the sampling interval is too wide and the auto-correlation function of PRBS sequence is not good, not like impulse response.
