PURPOSE:To shape the output waveform of a detecting circuit and to obtain an edge-emphasized waveform of the output waveform, by applying the output of a differentiating circuit to an adding circuit after full-wave rectification. CONSTITUTION:An input signal is detected by the detecting circuit 1 to obtain an output (a) with a voltage waveform (a). This voltage waveform (a) is differentiated by the differentiating circuit 3 to obtain an output (b) with a voltage waveform (b). The voltage waveform (b) is rectified by a full-wave rectifying circuit 4 to obtain an output (c) with a voltage waveform (c). Then, the output of the detecting circuit 1 and the output of the full-wave rectifying circuit 4, i.e. waveforms (a) and (c) are added together by the adding circuit 2 to obtain an output having the edge-emphasized voltage waveform. Thus, the edge-emphasized waveform of the output waveform of the detecting circuit is obtained. |
