The Q factor, or quality factor, is a dimensionless parameter that describes how underdamped an oscillator or resonator is, indicating its bandwidth relative to its center frequency. A higher Q factor signifies lower energy loss relative to the stored energy, resulting in sharper resonance peaks and greater selectivity in filtering applications.

The quality factor, also known as the Q factor, is a dimensionless parameter that describes how underdamped an oscillator or resonator is, and characterizes a resonator's bandwidth relative to its center frequency. A higher Q indicates a lower rate of energy loss relative to the stored energy, meaning the system is more selective in its frequency response and has a narrower bandwidth.

A dimensionless parameter is a pure number that characterizes a physical system, independent of the units of measurement. Such parameters often arise when normalizing equations, facilitating comparisons and simplifications across different systems and scales.

Underdamped oscillator

A resonator is a device or system that naturally oscillates at certain frequencies, known as its resonant frequencies, with greater amplitude than at others. It is used in various applications, from musical instruments to electronic circuits, to select or amplify specific frequencies while attenuating others.

Bandwidth refers to the maximum rate of data transfer across a given path, crucial for determining the speed and efficiency of network communications. It is a critical factor in the performance of networks, impacting everything from internet browsing to streaming and data-intensive applications.

bandwidth

Center frequency is the frequency at which the power of a bandpass filter or communication channel is maximized, serving as a reference point for the bandwidth's range. It is crucial in signal processing and telecommunications for optimizing the performance and efficiency of filtering systems and communication channels.

center frequency

Energy loss refers to the dissipation of energy from a system, often as heat, sound, or other non-useful forms, reducing the efficiency of energy transfer or conversion processes. Understanding and minimizing energy loss is crucial in optimizing systems for better performance and sustainability across various fields such as engineering, physics, and environmental science.

Selectivity refers to the ability of a system, process, or organism to preferentially choose or react with certain elements, compounds, or signals over others. This concept is crucial in fields like chemistry, biology, and engineering, where it impacts the efficiency, specificity, and outcome of reactions and processes.
