Elektronika II. - učebnice – Bezděk Miloslav (2018)

The textbook Electronics II fills the gap in the lack of textbooks for low-current fields. The revised second volume of the textbook Electronics II is intended for the 3rd year of industrial schools, the 2nd year of technical secondary schools, and vocational schools for fields with codes starting with the number 26. The content is designed for both learning needs and for introducing the specific topic through explanations of principles. The textbook is divided into five chapters. The first chapter deals with the creation of the electromagnetic field and its propagation into the surroundings. The middle part describes transmitting and receiving antennas. The last part of the chapter describes the use of microwaves – microwave ovens, descriptions and uses of radars, microwave weapons. The second chapter deals with electroacoustics. First, basic concepts from acoustics are explained, followed by the principles of operation of classical and wireless microphones. This is followed by a description of speakers, multi-channel reproduction systems, and sound reinforcement of spaces. The third chapter describes the principles of recording and reproducing sound – mechanical, optical (cinematography; methods of 3D projection; CD, DVD, and Blu-ray technologies) and magnetic (classic recording on magnetic tape, magnetoresistive sensors). The fourth chapter deals with the principle...
