Question

Quizplus · Accepted Answer

The PHA receives the output of the amplifier and determines if it falls within a selected energy range on the basis of the pulse height.The electronics within the PHA check the height of the pulse against lower and upper voltage levels.If the pulse height is within the defined range, the PHA puts out a standard-sized pulse that will be transmitted to a scaler or rate meter; otherwise no signal is generated.The PHA consists of three components: a lower-level discriminator, an upper-level discriminator, and an anticoincidence circuit that determines when the lower discriminator is triggered but not the upper energy discriminator, signaling that a pulse is received between the two windows.
