Scattering Parameters Tutorial: What Are They & What Do They Do?

What are S Parameters? The S-parameters, also known as scattering or S-matrix parameters, represent how RF energy moves through a multi-port network. It represents the linear properties of RF electronic components and describes how energy travels through an electric network. The S-parameter matrix calculates characteristics like gain, loss, impedance, phase group delay, and VSWR. S-parameters … Read more

Economic Dispatch Problem: What is it? (Security & MOE)

What is Economic Dispatch? Economic dispatch (also known as economic load dispatch or merit order) is defined as an online process that allocates the generation among the available generators to fulfil the load demand, which helps minimise the total generation cost. Economic dispatch uses efficient methods to operate power facilities, adhering to production and transmission … Read more

How to Find the DC Gain of a Transfer Function (Examples Included)

What is a Transfer Function? A transfer function shows how the input signal of a control system affects the output signal. A block diagram helps visualize this by using blocks for the transfer function and arrows for the input and output signals. A transfer function is a useful way to represent a linear time-invariant system. … Read more

ELI the ICE man: What is it (And What Does it Stand For ⛄️)

What is ELI the ICE man? ELI the ICE man is used to remember the relationship between current and voltage in an inductor and capacitor. ELI the ICE man stands for the fact that voltage [E] leads current [I] in an inductor [L] (that’s the ELI part) and current [I] leads voltage [E] in a … Read more

How to Calculate Equivalent Resistance (Series & Parallel Circuit Examples)

What is Equivalent Resistance? The equivalent resistance is defined as a point where the total resistance is measured in a parallel or series circuit (in either the whole circuit or in a part of the circuit). The equivalent resistance is defined between two terminals or nodes of the network. Equivalent resistance may sound complicated, but … Read more

Q Factor: What is it? (And How Do You Measure It?)

What is Q Factor? Q factor (also known as Quality Factor or Q-factor) is defined as a dimensionless parameter that describes the underdamped condition of an oscillator or resonator. The quality factor measures the performance of a coil, a capacitor, or an inductor in terms of its losses and resonator bandwidth. The Quality Factor was … Read more

Watts Law: What is it? Formula, Examples & Watt’s Law Triangle

What is Watts Law? Watts Law is defined as the relationship between power, current (amperage), and voltage dropin an electrical circuit. It states that the power in a circuit is the product of its voltage and current. Watts Law Formula The formula for Watts law can be given as follows. It gives the relationships between … Read more

SWR Meter: What Is It & How To Use It

What is an SWR Meter? A standing wave ratio meter – also known as an SWR meter, ISWR meter (current “I” SWR), or VSWR meter (voltage SWR) – is defined as a device that measures the standing wave ratio (SWR) in a transmission line. The SWR meter indirectly measures the degree of mismatch between a … Read more

Cutoff Frequency: What is it? Formula And How To Find it

What is Cutoff Frequency? Cutoff frequency (also known as corner frequency, or break frequency) is defined as a boundary in a system’s frequency response at which energy flowing through the system begins to be attenuated (reflected or reduced) rather than passing through. The cutoff frequency or corner frequency in electronics is the frequency either above … Read more
