Introduction to Electronic Filters is your comprehensive guide to understanding designing
and applying first-order electronic filters using resistors capacitors and inductors. Whether
you are a student maker or educator this book demystifies the theory behind RC and RL
filters and bridges the gap between concepts and real-world applications through simulation and
experimentation. From the basics of frequency response and phase shift to hands-on breadboard
builds and Python-based simulations this book offers a deeply practical learning experience.
You will learn to analyse filters using Bode plots and phasors and explore applications in
audio tone shaping sensor signal conditioning noise reduction and power supply filtering. As
you progress you'll build measure simulate and tune filters using modern tools like
CircuitLab Python and the Analog Discovery 3. Each chapter includes thoughtfully crafted
activities that reinforce learning by doing - designing filters for specific tasks simulating
dynamic behaviour and observing how theory translates into performance. Inside you'll find: A
clear introduction to the fundamentals of electronic filters Detailed explanations of RC and RL
filters cutoff frequency and phase Guided activities using both simulation and hardware tools
Real-life applications in audio sensors power supplies and more A beginner-friendly primer
on Python and algebra for electronics Whether you're working through simulations or
experimenting with real components on your workbench this book will help you develop a solid
understanding of electronic filters and their role in practical circuits.
