Spurious-Free Dynamic Range (SFDR) is a critical parameter in signal processing and communications, indicating the range over which a system can process signals without distortion from spurious signals or noise. It is defined as the ratio between the amplitude of the desired signal and the amplitude of the largest spurious signal within the bandwidth of interest.

Signal processing involves the analysis, manipulation, and synthesis of signals such as sound, images, and scientific measurements to improve transmission, storage, and quality. It is fundamental in various applications, including telecommunications, audio engineering, and biomedical engineering, where it enhances signal clarity and extracts useful information.

Signal distortion refers to any alteration of a signal's original waveform or other characteristics as it travels through a transmission medium. It can degrade the quality of the signal, leading to errors in data transmission and reduced communication efficiency.
