When it comes to technology, the term "relating to or using signals over a range of frequencies" is often referring to the concept of frequency modulation (FM). FM is a method of transmitting information by varying the frequency of a carrier wave, rather than the amplitude as in amplitude modulation (AM).

FM signals are able to carry more information and are less susceptible to interference than AM signals. This is because changes in the frequency of the carrier wave are less affected by noise and other distortions in the signal. FM signals are commonly used in radio broadcasts, telecommunications, and radar systems.

One of the key advantages of using signals over a range of frequencies is the ability to transmit a wider range of information. By modulating the frequency of the carrier wave, a single signal can carry multiple channels of information simultaneously. This is why FM radio stations are able to broadcast multiple channels within the same frequency band.

In addition to the increased bandwidth and information capacity, signals over a range of frequencies also offer improved signal quality and reliability. FM signals are less prone to fading and interference, making them a preferred choice for high-fidelity audio transmissions and long-distance communications.

From a practical standpoint, signals over a range of frequencies can be easily transmitted and received using a variety of devices, from traditional radio receivers to modern smartphones. The widespread availability of FM technology has made it a versatile and widely-used method of communication in today's digital age.

Overall, the use of signals over a range of frequencies offers numerous benefits in terms of signal quality, bandwidth, and reliability. Whether you're tuning in to your favorite radio station or sending data over a telecommunications network, the use of FM signals provides a robust and efficient method of transmitting information over long distances.
