The processes of integration and differentiation of stresses by RC-chains are considered. Based on the method of complex amplitudes, formulas for a complex transmission coefficient for high and low frequency filters. are obtained. Before performing laboratory work, the processes of integration, differentiation and transmission of input voltages are simulated using the computer programs Electronics Workbench and Multisim12.. 0. In the course of the work, students determine the transmission coefficient modules and phase shifts between input and output voltages using digital functional generators and dual-channel oscilloscopes in the frequency range up to 10 MHz. Designed for students studying in the fields of natural science and engineering profiles, to form basic knowledge in electrical engineering and radio electronics .
