In a CFD, the unipolar input signal is turned into a bipolar signal by an appropriate electronic chain. This is done by splitting the input signal with different ratio. One of the signals experiences a certain delay and gets inverted, while the other gets attenuated. Finally both signals are again added to form the CFD bipolar signal.  4, record 1, English, - constant%20fraction%20discriminator

Le discriminateur à fraction constante. Pour une fenêtre d’énergie réglée, soit sur 1,28 MeV [mégaélectronvolt], soit sur 511 keV [kiloélectronvolts], il génère une impulsion logique suivant le principe de discrimination à fraction constante pour dater la détection du gamma indépendamment de la forme de l’impulsion envoyée par le photomultiplicateur. Plus précisément, le signal de sortie du photomultiplicateur est divisé en deux parties; la première est retardée et inversée et la deuxième est atténuée d’une fraction constante. Les deux signaux sont ensuite additionnés pour former un signal bipolaire caractérisé par un passage à zéro temporellement indépendant de l’amplitude du signal initial.  3, record 1, French, - discriminateur%20%C3%A0%20fraction%20constante

Energy spectroscopy. For energy analysis the output current pulse from a PMT [photomultiplier tube] or from a semiconductor detector is often applied to a charge-sensitive preamplifier. The preamplifier produces a voltage pulse with a peak amplitude that is proportional to the total charge in the current pulse, which is proportional to the energy absorbed from the incident radiation. Amplifiers and filters are used to expand the range of the peak amplitude and to shape the signal from the preamplifier, a process that maximizes the signal-to-noise ratio for the system. For energy analysis the peak amplitude of the shaped pulse represents the information of interest. Discriminators and single-channel analyzers(SCA) can be used, following the signal shaping system, to determine the presence of certain energies of detected radiation. A discriminator produces an output logic pulse if it's input signal exceeds a preset threshold level. An SCA produces an output logic pulse if the peak amplitude of it's input signal falls within the energy window that is established with two preset threshold levels.  1, record 2, English, - energy%20spectroscopy

Total neutron counting accepts all pulses arising from neutron reactions(events) in the sensitive volume of a detector. No attempt is made to isolate events that occur nearly simultaneously as is done in coincidence counting... All detector events producing an amplifier output pulse with an amplitude greater than a threshold set by the integral discriminator are counted for a set time in a scaler.  1, record 4, English, - total%20neutron%20counting

A ratio detector... is a discriminator operating on the same principle as the Foster-Seely discriminator but less sensitive to amplitude modulation. The coupling circuit and the addition of the primary voltage to the center tap of the secondary may be identical to the corresponding portion of a Foster-Seely discriminator. However, in the ratio detector, the two diodes are connected so that their load voltages are additive rather than subtractive.  3, record 5, English, - ratio%20detector

An improved demodulator, known as a phase-shift or Foster-Seely discriminator... is sensitive to amplitude variations, or modulation, as well as to frequency modulation....
