From the preface
    

Topics relating to the field of linear electronics have been incorporated for many years in the curricula of the Faculty of Electrical Engineering in Belgrade and other technical universities in Serbia . However, there is still lack of textbooks and collections of solved problems in Serbian language. Taking part in, Authors of this collection have been teaching Linear electronics at the Faculty of Electrical Engineering in Belgrade for several years, and this collection is the result of their work. Almost all included problems are from the final exams, and are presented here in the same or the similar form. Hence, the collection is aimed primarily for the students of the Faculty of Electrical Engineering in Belgrade for the course of Linear electronics, but also will be helpful to students of other Serbian universities. Moreover, it can be used as a source of useful solutions for the amplifier and filter design problems in the engineering practice.

The first chapter deals with the problems related to frequency limitations and noise in amplifier circuits. Approximate methods for the frequency domain analysis of the amplifier performance are presented. Special attention is devoted to the slew-rate limitation in operational amplifiers. Methods for the noise analysis in the linear semiconductor circuits are also included.

The second chapter includes problems dealing with the amplifier stability and frequency compensation. Solved examples involve all significant compensation methods in the amplifier or feedback circuit. Except for several examples at the end of the chapter, problems contain amplifiers or amplifier stages defined only by the external parameters. This approach gives attention to the essence of the problem, reducing circuit evaluations and calculations to the acceptable level.

Analogue filter design is covered by the problems in the third chapter. The problems include all design steps, from the specification of the margins to the passive and active realizations, including all standard biquadratic sections used in the modern practice.
