Pulse
processing:
Thresholding & Peak detection
•Since the analog pulse is very short (microseconds
typically) the only way to retain
this pulse is to charge a capacitor
•
•The capacitor serves as a storage device for a
signal
•
•For peak detection, the capacitor is charged from a
circuit that allows only a build
up of signal (a diode achieves this) and
the final or peak signal represents the maximum signal obtained
