Abstract:
1. A biological signal measuring apparatus configured to detect an oscillatory wave that is generated by a biological body and to calculate data of the vibration frequency per unit time, comprising: a pressure sensor, configured to detect an oscillatory wave that is generated by a biological body as a sensor signal and to output the sensor signal having an amplitude that is larger than an amplitude of a reference value signal as an oscillatory wave signal; an oscillatory wave period measuring part configured to measure a time interval of the oscillatory wave signals and to output periodic data; a group memory means configured to collect a plurality of the periodic data and to store the plurality of the periodic data as a group signal that is a data group to be measured; and a vibration frequency calculation means configured to calculate data of the vibration frequency based on the group signal that has been stored into the group memory means, wherein the vibration frequency calculation means comprises:
