Impedance (Z) is the total opposition that a circuit offers to alternating current (AC) flow when a specific voltage is applied.
Unlike simple resistance, impedance is a complex quantity comprising resistance (the real part) and reactance (the imaginary part, representing inductive or capacitive effects). In the frequency domain, impedance is represented as a phasor, accounting for both magnitude and phase shift between voltage and current. In DC circuits, impedance reduces to pure resistance with zero phase angle.

| Symbol | Z |
| Unit | Ohm (Ω) |
Impedance management is critical in high-speed hardware design and signal integrity. In modern PCB manufacturing, controlled impedance ensures that high-frequency signals reach their destination without reflections, which is vital for PCIe or DDR5 performance.
Complex Domain Analysis
Mathematical modeling of impedance using the j-operator allows engineers to optimize filter performance and resonance characteristics in electronic systems.
Key Advantages
- Maximum power transfer through impedance matching.
- Minimized signal reflections in high-frequency transmission lines.
- Improved electromagnetic compatibility (EMC).
Note: Impedance is the cornerstone of modern AC circuit theory and high-frequency design.
