... noise has its most deleterious effect on reception quality when it occurs in the input circuitry of the receiver, since this is usually where the basic signal-to-noise ratio is established. The generation of noise in this area is principally caused by thermal agitation in resistive input components.

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 10, English, - energy%20spectroscopy

Pulse Compression. In collecting the SAR data, a long-duration linear FM [frequency modulation] pulse is transmitted. This allows the pulse energy to be transmitted with a lower peak power. The linear FM pulse has the property that, when filtered with a matched filter, the result is a narrow pulse in which all the pulse energy has been collected to the peak value. Thus, when a matched filter is applied to the received echo, it is as if a narrow pulse were transmitted, with its corresponding range resolution and signal-to-noise ratio.  3, record 20, English, - pulse%20compression

Traitement en distance [-] compression d'impulsion. Pour obtenir une résolution en distance satisfaisante (de l'ordre de quelques mètres) il est nécessaire que l'impulsion ait une durée d'émission très brève (quelques nano-secondes). Or, une telle durée conduirait à émettre une impulsion de puissance très élevée afin d'obtenir en retour un signal suffisant compte tenu des amortissements lors du trajet, du coefficient de rétrodiffusion des cibles, et des traitements au niveau de l'antenne [...]. Les valeurs d'énergie nécessaires sont difficilement compatibles avec les instruments satellitaires disponibles. La finesse de résolution est donc obtenue en utilisant une technique dite de modulation de fréquence.

La preacentuación consiste en una modificación en la característica de la ganancia/frecuencia de un canal, dando normalmente como resultado un incremento de las amplitudes relativas de los componentes de la señal de frecuencia más alta. La desacentuación, que se aplica a la salida de un canal, es la operación inversa a la preacentuación, con la que debe estar asociada con el fin de restablecer la relación original de los componentes de la señal.  1, record 27, Spanish, - preacentuaci%C3%B3n%2Fdesacentuaci%C3%B3n
