When most of us hear the word electronics, we think of televisions, laptop computers, cell phones, or iPods. Actually, these items are electronic systems composed of subsystems or electronic circuits, which include amplifiers, signal sources, power supplies, and digital logic circuits. Today, electronics generally involves transistors and transistor circuits.
This course involves an in depth study of analog electronics involving electronic devices such as Diodes, BJT, JFET, MOSFET and Oscillators in line with the course described by Mumbai University.
