【摘要】 用频域交调波平衡法分析有源滤波器的非线性交调失真，并以一个双频激励的二阶带通有源滤波器为例，给出了交调失真的计算和测量结果，文中还就计算效率和分析精度对频域交调波平衡法和已有的时域谱平衡法进行了比较．更多还原

【Abstract】 The frequency-domain intermodulation balance method is presented for nonlinear intermodulation distortion prediction in active filters. As an example, a second-order bandpass filter with two-tone input is analyzed and measured. This technique and the time domain spectral balance are compared with respect to accuracy and computational efficiency.更多还原
