Final answer:
Wave pulses carrying digital signals offer clearer data transmission, data compression capabilities, and enable a higher volume of information to be transmitted quickly, especially with high frequencies and via optical fibers.
Step-by-step explanation:
Wave pulses can carry digital signals, which is considered a superior method for signal transmission for several reasons. Digital signals represent information as sequences of binary ones and zeros, allowing clearer transmission, especially when the signal is weak. This binary representation lends itself to being processed by computer algorithms to compress data, thereby transmitting more information within each frequency range.
Electromagnetic waves, such as microwaves, are used for digital signal transmission, often modulating the carrier wave's amplitude, frequency, or phase. The use of higher frequencies, like those in microwaves, can convey more data per unit of time, making them well-suited for high-bandwidth communications like satellite and long-distance transmissions. However, they require a clear line of sight due to their short wavelengths.
Furthermore, in the realm of high-frequency communication, optical fibers also significantly enhance transmission capabilities. Optical fibers have low loss and high bandwidth, allowing light from lasers to travel vast distances without significant signal attenuation and support more concurrent transmissions than traditional copper-based systems.
