Episode 1 - What is Impedance?

This section explains the concept of impedance. The unit of impedance of a capacitor or coil is "Ω", but it does not consume power like a resistor. The meaning of impedance for capacitors and coils will be explained in an easy-to-understand manner.

Episode 2 - What is Characteristic Impedance?

The meaning of characteristic impedance is explained by comparing it to a waterway. Reflected waves are generated when traces with different characteristic Impedances are connected. The mechanism by which reflected waves are generated will be explained in an easy-to-understand manner by comparing it to water flowing in a waterway.

Episode 3 - What is a Transmission Line?

The mechanism by which signals and electric power are transmitted over transmission lines is explained in an easy-to-understand manner by comparing it to water flowing in a waterway. The lecture does not use difficult mathematical formulas, but uses the image of water flowing in a waterway to help the viewer understand transmission lines.

Episode 4 - Characteristic Impedance Measurement Methods

This article provides a detailed explanation of measuring characteristic impedance, including practical examples. It covers reviewing characteristic impedance, measuring it in both the time and frequency domains, and interpreting the measurement results.

Episode 5 - Using TDR (Time Domain Reflectometry) Notes on Characteristic Impedance Measurement

In Episode 4, the discussed topic was the measurement of Characteristic Impedance (Zc), and this time, there will be an explanation of the points to consider when measuring Zc using TDR.
