摘要: Provided is a laryngeal stroboscope using voice signals. The includes photography unit for photographing patient's vocal cords and light source illuminating part to be photographed, microphone sensing the voice, high-pass filter passing signals of 100 Hz or more among output from microphone, low-pass removing harmonic components only signal in fundamental frequency band, peak detector detecting obtaining pitch, controller controlling intermittently emit response operate according whether not emitted.
