Frequency synthesis is the process of generating a range of frequencies from a single reference frequency. This technique is commonly used in telecommunications and signal processing to create stable and precise signals. By combining various techniques, such as phase-locked loops (PLLs) and digital signal processing, engineers can produce frequencies that are multiples or fractions of the reference frequency. One of the key applications of frequency synthesis is in the design of radio transmitters and receivers. These devices rely on synthesized frequencies to ensure clear communication over long distances. Additionally, frequency synthesis plays a crucial role in synthesizers used in music production, allowing musicians to create a wide variety of sounds and tones.
