发明名称 Circuit arrangement for echo suppression
摘要 In an adaptive filter a frequency domain filter is used to enhance the convergence properties of the filter for strongly correlated signals. To reduce the amount of delay in the filter the impulse response of said filter for small values of time is generated by a time domain filter, and said impulse response for larger values of time is generated by a frequency domain filter.
