从时间域与频率域角度通过FFT、矩形窗函数等运算对信号采样、混叠、频谱泄漏等的实验观察提出Tektronix MSO2000型混合信号示波器为数据处理和分析提供大量原始实验数据,而避免了实验过程中大量、繁琐的数据计算处理的方法。通过实验测试进一步说明所提出方案的有效性。
Experimental observation of signal sampling, aliasing, spectrum leakage and so on from the perspective of time domain and frequency domain through FFT, rectangular window function, etc. Tektronix MSO2000 Mixed Signal Oscilloscope provides a large amount of original experimental data for data processing and analysis, The process of massive, cumbersome data processing methods. The effectiveness of the proposed scheme is further illustrated through experimental testing.
