Abstract
A stroboscope device for diagnosis of larynx emissions. The system uses a saw tooth wave for generating in synchronization with a vocal cord vibration saw tooth waves whose voltages are constant in minimum and maximum values. A reference voltage generating circuit is used whose output voltage is variable and a discharge tube light emission control signal generating circuit compares the instantaneous voltage of each saw tooth wave with the output of the reference voltage generating circuit to generate a discharge tube light emission control signal in a phase shift range with respect to said vocal cord vibration. The discharge tube light emission control signal may be generated in a desired phase of said vocal cord vibration every period of said vocal cord vibration or at a repetition rate of multiple periods of the vocal cord vibration.
