专利汇可以提供Automatic waveform equalizer专利检索,专利查询,专利分析的服务。并且PURPOSE:To remove DC offsets with a simple constitution by inserting a passive filter cutting off DC between a correlator and an error signal generating circuit or between the input terminal of a transversal filter and the correlator. CONSTITUTION:An input x(t) is inputted to the transversal filter 1 and the correlator 4. An output y(t) from the transversal filter is outputted from an output terminal and also inputted to the error signal generator 3, which compares the input with a signal (r) from a reference signal source 2 to generate an error signal e(t). Then, the passive filter 50 consisting of a capacitor 5a and a resistor 52 removes a DC offset from the signal e(t) and outputs a signal e0(t) and the correlator 4 finds out the correlation between the signal e0(t) and another signal x(t). On the basis of the correlated result, a tap gain memory 6 is compensated and the transversal filter 1 is automatically controlled. The passive filter can remove an offset also from the signal x(t) in stead of the signal e(t).,下面是Automatic waveform equalizer专利的具体信息内容。
