Peak detector
Abstract
Abstract A PEAK DETECTOR NETWORK CONSISTS OF A CAPACITOR AND A DIODE ARRAY. THE SIGNAL TO BE DETECTED IS PASSED THROUGH THE CAPACITOR AND IS THEN SHORTED TO GROUND THROUGH THE DIODE ARRAY. THE DIODE ARRAY WILL TEND TO SHORT OUT THE SIGNAL EXCEPT WHEN THE INPUT SIGNAL TENDS TO CHANGE THE DIRECTION OF CHARVE OF THE CAPACITOR. AT THE TIME OF THE CHARGE THE POLARITY ACROSS THE DIODES WILL CHANGE THEREFORE GIVING AN OUTPUT SIGNAL. CIRCUITRY IS ALSO PROVIDED WHICH ENABLES THE PEAK DETECTOR TO HANDLE SIGNALS HAVING A WIDE RANGE OF AMPLITUDES. FURTHER CIRCUITRY IS PROVIDED TO GIVE UNIFORM RECTANGULAR WAVE OUTPUT REGARDLESS OF THE HEIGHT OR POLARITY OF THE INPUT. ALSO PROVIDED IS A TRIGGER ARRANGEMENT WHICH DISABLES THE OUTPUT CIRCUITRY FOR ANY SIGNAL WHICH FALLS BELOW A GIVEN LEVEL.
