Laboratory of Electronics 1

Course Description

The purpose of this course is to give the students the practical knowledge about analog signal processing procedures in time and frequency domain, the ability to realize practical circuits, the practical knowledge about passive and active microwave circuits, microwave CAD software and test equipment, about audio technology, audio transfer and recording systems, audio signal processing as well as measurements on audio systems. The course offers individual practical experience about the concepts that are taught in Analog and Mixed signal processing, Microwave Engineering and Audiosystems.

General Competencies

Practical knowledge about laboratory instrumentation, and procedures for measurement the parameters and analysis of various analog signal processing circuits, ability to create projects and solutions for different signal processing tasks, and to develop and realize simple SP circuits and to simulate linear and nonlinear analog circuits using CAD programs. Deep understanding of microwave CAD simulation software allowing students to verify results of the design-oriented problems in Microwave Engineering. Practical skills to design basic microwave circuits including a microwave laboratory experience. Practical knowledge about audio signal transfer in audio communications through different audio systems.
