What are the advantages of using digital waves over analog signals?
kvasek [131]

Answer:

What are the advantages and disadvantages of digital over analog?

Do you want to learn more about crypto?

“Advantages of Digital Communication. The effect of distortion, noise, and interference is much less in digital signals as they are less affected. Digital circuits are easy to design and cheaper than analog circuits. The hardware implementation in digital circuits, is more flexible than analog.” In general, digital is far easier to handle and has (virtually) unlimited precision (limited only by hardware constraints and compute time).

Analog computation takes place at a significant portion of the speed of light (the time it takes for an electrical signal to traverse a circuit). However, it is almost impossible to correct completely for noise, and precision is limited to three (or at most four significant digits).
