Why you should care about frequency response When someone says, “What does your system do at high frequency?” they’re really asking about frequency response. And the most compact, engineer-friendly way to see that response is the Bode plot: two…
Understanding Transfer Functions: From Basics to Advanced Examples Transfer functions are a key concept in systems engineering, especially in control theory and signal processing. Whether you’re designing an amplifier circuit or a robotic arm, transfer functions help you understand…
Mastering Circuit Analysis with Laplace Transforms Step by Step If you’ve ever found solving differential equations in circuits messy or slow, you’re not alone. The Laplace Transform is one of the most powerful tools electrical engineers use to simplify…
Real and Reactive Power in 3-Phase AC Systems: A Practical Guide If you’re working with 3-phase power systems—whether you’re an engineer, technician, or student—understanding how to calculate real (active) and reactive power is essential. It’s not just about crunching…
Line Voltage, Phase Voltage, and Line Current: Explained Simply If you’re diving into the world of 3-phase electrical systems, one of the first things you’ll hear about is the relationship between line voltage, phase voltage, and line current. It…
What Are Delta (Δ) and Wye (Y) Connections in Three-Phase Power? In electrical engineering, especially in industrial settings, three-phase power is the standard for distributing large amounts of electricity. It’s more efficient than single-phase systems and supports heavy loads…
Understanding Q Factor and Bandwidth in Resonant Circuits If you’re diving into the world of electronics or RF systems, you’ve probably run across the terms Quality Factor (Q) and Bandwidth. These aren’t just buzzwords—they’re essential to understanding how resonant…
Frequency Response and Resonance in Series and Parallel RLC Circuits When we talk about AC circuits, one of the most fascinating topics is how the circuit responds to different frequencies. This is where frequency response and resonance come into…
