Simple Counting System

A basic measurement in many physics experiments is a simple counting of the number of pulses from a detector. In this setup, the analog signal from a detector is amplified by the preamplifier, shaped, and further amplified by the amplifier. The resulting analog signal is then sent through the low-level discriminator that delivers a signal for every input pulse with amplitude greater than the threshold value. The signal is then sent to the timer/scalar that counts each arriving pulse for a giving counting period T preset in the timer section. Discriminator serves the dual purpose of excluding low-level noise in analog suit and shaping the accepted signal to a form suitable for the scalar to accept.
