Provided is a method and apparatus for measuring a biosignal. The biosignal measurement method may include measuring, at a biosignal measurement apparatus, a biosignal using a biosignal measurement sensor processing, at the biosignal measurement apparatus, the biosignal and converting the biosignal to a pulse signal using a first voltage distribution time constant circuit and a waveform converter and counting, at the biosignal measurement apparatus, the pulse signal using a counter and generating first biometric information. The first voltage distribution time constant circuit may filter a signal of a specific frequency band from the biosignal based on voltage distribution using a series resistance included in the first voltage distribution time constant circuit.
