Analog Electronics is a practical, concept-driven guide to the behavior and application of electronic circuits whose signals vary continuously with time. It begins with voltage, current, resistance, capacitance, inductance, and semiconductor fundamentals, then moves through diodes, transistors, amplifiers, operational amplifiers, feedback, oscillators, filters, power stages, regulators, data converters, and troubleshooting.
The goal is not to memorize isolated equations. Each topic is organized around three questions: What does the circuit do? Why does it behave that way? How can an engineer measure and improve it? This approach is useful for diploma and degree students, technicians, maintenance engineers, hobbyists, and anyone preparing for technical interviews.
Throughout the book, practical design thinking is emphasized: choose sensible operating points, understand loading, control heat, protect components, measure before replacing parts, and compare calculated behavior with actual measurements.
Learning Outcomes
Explain the electrical quantities and semiconductor principles behind analog circuits.
Analyze diode, BJT, FET, MOSFET, amplifier, op-amp, filter, oscillator, and regulator circuits.
Use gain, bias, impedance, frequency response, feedback, and stability concepts in design decisions.
Read waveforms and use a multimeter and oscilloscope to locate common faults.
Apply safe, practical engineering judgment when selecting components and validating a circuit.
About the Author
Chetan Singh Sendra is an engineering professional with a practical interest in electrical and electronic systems, industrial maintenance, technical learning, and engineering education. His approach combines fundamentals with field-oriented problem solving: understand the circuit, identify the failure mechanism, measure the evidence, and then choose the corrective action.
This book reflects that practical philosophy. It is written to make analog electronics approachable for learners who want to connect classroom equations with actual components, instruments, control panels, machines, and industrial applications.
The author’s objective is to encourage disciplined learning, safe experimentation, and continuous improvement. Readers are encouraged to verify calculations, consult component datasheets, and develop their own laboratory observations rather than treating any single example as a substitute for engineering judgment.
