Designing, simulation and testing of low current passive filters used in the didactic activity

摘要

The paper is focused on the simulation, realization and testing of a low current RC passive filters. The analysis relies on low pass and high pass first order passive filters. Staring from these filters other two RC circuits can be achieved: band pass and band stop filters. Based on the results yielded by the design and respectively by simulation, an integrated experimental platform was realized. In the second part of the paper, the simulation results have been validated by experimental results. The realized platform is useful in the didactic activity to understand the role of these filters in an electrical circuit.
