Abstract：The time-domain characteristics of weights and errors in analog adaptive interference cancellation system with integral control and low-pass control are analyzed. Under low-pass control, which is different with integral control, the residual error is not zero. But the convergence speed of low-pass control is faster than that of integral control. The analysis of neglecting high frequency can not reflect the different damp characteristics and the calculations are approximate. Adjusting the time constant of low-pass filter instead of increasing the gain out of the low-pass filter can improve the interference cancellation ratio and maintain the 3dB bandwidth.
