Final answer:
The statement is false. In DSL, attenuation is the loss of signal strength and it affects higher frequency signals more severely, making them less effective over distance. Higher frequencies cannot be used more effectively when more attenuation occurs.
Step-by-step explanation:
The statement about DSL and attenuation:
The statement about DSL and attenuation is false. Attenuation refers to the loss of signal strength as it travels over a distance. In the context of DSL, which stands for Digital Subscriber Line, a type of internet connection that uses telephone lines, attenuation negatively affects signal quality. As the signal travels further from the source or through different types of media, it gets weaker, particularly at higher frequencies.
DSL services often use a range of frequencies, and the higher frequencies, which can carry more data, do not travel as far or as effectively as lower frequency signals due to this very reason. Therefore, when designing and implementing DSL networks, engineers have to balance the need for higher bandwidth with the limitations posed by signal attenuation.
