ABSTRACT:
Waveform converting circuits are disclosed which eliminate errors in data reproduction due to the transitional response of low or high pass filters even if the data signal contains a D.C. component. The converting circuits have a comparator with first and second input terminals. The comparator produces a "1" or "0" output depending on the comparison of the voltages of input signals fed to these first and second input terminals. In one type of converting circuit, a low pass filter is connected between the signal input terminal and the second input terminal of the comparator, while the signal input terminal is directly connected to the first input terminal of the comparator. A feedback circuit including a low pass filter is connected between the output and the second input terminals of the comparator. In another type of converting circuit, a high pass filter is connected between the signal input terminal and the first input terminal of the comparator, and a limiter is connected to the output of the high pass filter. A feedback circuit is provided between the output and either the first or second input terminals of the comparator.
