本文给出了考虑噪声和非线性时的 ACD 传输模型。推导出时域量化噪声对谐波影响的公式。同时指出谱平均方法可以明显地减小量化噪声对谐波分析的影响,提高动态非线性测量的灵敏度和精度。最后给出计算机模拟测试结果。
In this paper, ACD transmission model considering noise and nonlinearity is given. The influence of time-domain quantization noise on harmonics is deduced. At the same time, it is pointed out that the spectral average method can obviously reduce the influence of quantization noise on harmonic analysis and improve the sensitivity and accuracy of dynamic nonlinear measurement. Finally, the computer simulation test results are given.
