Abstract
An object of this invention is to provide a biological signal measuring device which is able to reproduce a biological signal waveform with high fidelity which is detected from an object under examination. The biological signal measuring device comprises: an amplifier and a filter forming a waveform leading section which has a filter characteristic represented by a predetermined transfer function and filters a biological signal waveform detected from an object under examination; a waveform cutting section for extracting a desired part of the biological signal waveform outputted by the waveform leading section; and a reverse correction circuit for subjecting the part thus extracted to reverse correction with a transfer function which is opposite to that of the waveform leading section.
