Digital manages noise better than Analog. Through binary code, signals are sent as 0’s and 1’s. A digital signal is usually defined such that any voltage below a certain limit represents a 0, while any voltage above the limit represents a 1. This cutoff effectively reduces the impact of noise. But analog when signals are amplified, they can also boost the noise, so that then makes it harder to get back the original quality . So as more noise builds up, the output can become more distorted .
