What is sfdr?

SFDR stands for Spurious-Free Dynamic Range, which is a measurement used in signal processing to determine the ratio between the desired signal and the spurious or unwanted signals in a system. It is an important parameter in analog-to-digital converters, digital-to-analog converters, and other communication systems.

SFDR is typically expressed in decibels (dB) and represents the maximum amplitude of a spurious signal that can be present without degrading the quality of the desired signal. A higher SFDR value indicates a better performance in terms of signal purity and integrity.

Improving SFDR can be achieved by optimizing the design of the system, including the selection of components, signal processing algorithms, and filtering techniques. High SFDR is crucial in applications where accuracy and precision are required, such as in high-resolution imaging systems, radar systems, and data communication networks.
