The Electronic Devices and Circuit paper at the CBSE level is important for a thorough knowledge and understanding of the concepts of mechanism that help devices work. The paper has 8 questions in all and all of them are mandatory. Each question will fetch you 5 marks and in some questions you will find alternatives as well. Some of the topics covered in this are working of a direct coupled amplifier and its limitation, working of typical circuit of transformer coupled multistage amplifier and sketching of its frequency response, understanding the principle of working in the push pull amplifier, its advantages and disadvantages, function of transistor as a switch, the principle of working of crystal oscillator, sketching of low frequency hybrid model in the CE configuration, concepts behind the working of AC load line & show how it is used in the understanding of phase reversal of output voltage in terms of the input voltage, sketching and diagrammatic representation of a R.C coupled multistage amplifier, differences between lower crossover frequency and upper crossover frequency, bandwidth, distortion and gain stability of an amplifier.
