<p>PURPOSE: To provide an analog signal analyzing method and a circuit which executes the method applicable to coin sorting machine for, specially, game machine, an automatic vending machine and a general coin operation equipment of the same kind, and which can guarantee high reliability for sorting when they are applied to a machine which need to have similar performance. CONSTITUTION: The analog signal analyzing method establishes various measurements areas TA, TB, TC, etc., according to variation in the gradient of an analog signal SA to generate a digital signal SD corresponding to the variation in gradient of the signal, and the electronic circuit which executes the said method consists of an operational amplifier which compares the analog signal SA with a signal delayed slightly behind the analog SA and is equipped with a delay circuit.</p> |
