AbstractA binary threshold value setting circuit comprises: a first detecting section to detect the positive polarity side of an input signal, a second detecting section to detect the negative polarity side of the signal; a first envelope detecting section to perform an envelope detection to the signal detected by the first detecting section, a second envelope detecting section to perform an envelope detection to the signal detected by the second detecting section, a threshold value setting section to generate a signal at a level between the level of the signal which has been envelope detected by the first envelope detecting section and the level of the signal which has been envelope detected by the second envelope detecting section, and a capacitor connected between the output side of the first detecting section and the output side of the second detecting section.
