Abstract:
1. A percent body fat measuring apparatus comprising: first and second electrodes with which a living body is brought into contact; a detection resistor of which one terminal is connected to the second electrode; a signal generator which produces a measurement signal and applies a produced measurement signal between the first electrode and the other terminal of the detection resistor; a level detector for detecting the level of a signal which develops between the terminals of the detection resistor and is an object of detection; and a percent body fat computer for determining percent body fat on the basis of a result of detection operation performed by the level detector, wherein a measurement signal produced by the signal generator is analogous to a half-wave waveform; wherein the level detector detects the level of a waveform analogous to a half-wave of the signal to be detected; wherein the signal generator includes; wherein the level detector includes: wherein the pulse generator includes:
