Abstract

PURPOSE:To shorten the convergence time and improve the equalization degree in the frequency region, by providing a means of monitor the waveform obtained by differentiating the adding circuit output or extracting difference of the adding circuit output. CONSTITUTION:The input TV signal is input to delay line 5 with taps consisting of delay line group 3 of delay quantity tau from input terminal 1, and respective tap outputs are controlled by tap gain control circuit group 4 connected to respective taps and are added by adding circuit 8 and are output. This output signal is led to output terminal 11 through difference or differentiating circuit 10 and is monitored by an oscilloscope and so on to adjust the pertinent tap gain control circuit so that the waveform may be as shown by the dotted line.
