Final answer:

Digital signals are more reliable in transmitting information than analog signals due to their ability to be easily amplified and regenerated without losing the integrity of the signal, their built-in error correction mechanisms, and their ability to be compressed and decompressed for efficient data transmission.

Step-by-step explanation:

Digital signals are more reliable in transmitting information than analog signals due to several factors. One factor is that digital signals can be easily amplified and regenerated without losing the integrity of the signal. This is because digital signals are represented by a discrete set of values, usually binary ones and zeros, which can be accurately reproduced.

On the other hand, analog signals are continuous and can be easily distorted or degraded by noise, interference, and attenuation. The continuous nature of analog signals makes them more susceptible to errors during transmission. In contrast, digital signals have built-in error correction mechanisms that can detect and correct errors, ensuring more reliable data transmission.

Additionally, digital signals can be easily compressed and decompressed, allowing more data to be transmitted in a given bandwidth. This is particularly useful in applications such as video streaming or file transfer where large amounts of data need to be transmitted efficiently.

Answer:

Digital signals are a more reliable form of transmitting information because an error in the amplitude or frequency value would have to be very large in order to cause a jump to a different value. Signals are composed of infinite possible values. Signals are composed of only two possible values: 0 or 1.
