The manual is intended for practical classes in analog electronics and course design. The principles of operation of circuits on passive and active elements are considered in detail. Examples of calculations of analog circuits on transistors and operational amplifiers used in modern technology are considered: calculation of amplifier stages on DC and AC transistors, op-amp amplifiers, comparators, multivibrators, harmonic oscillation generators, GLIN, transistor switches. Calculation of recommended assignment for course work is given.
