Course abstract

The course covers problems connected with analogous electronics. Basic information about construction of semiconductors and operational principles of electronic elements is given in the first part of the course. Second part discusses various small signal and power transistor amplifier circuits. Student’s theoretical knowledge is improved in laboratory by working with discrete semiconductor elements and circuits and by performing graphical and analytical calculations.
