This study subject consists of several practical exercises and experimental demonstrations. The goal is to teach the students how to connect and operate electronic modules for ionizing radiation detector signal processing. NIM standard modules will be used predominantly. Additionally, the work with osciloscope will be exercised intensively. Graduates will be able to design, build and operate simple electronic circuit using NIM standard modules. This circuit should perform required duty, selected by the teacher. It is recommended to absolve the subject in the same semester as subject Instrumentation for Radiation Measurements.


Required prerequisities are 16ZPRA, 16DETE.
