Is noise amplified when a digital receiver is used?

Noise can be amplified in a digital receiver due to the quantization process, where continuous signals are converted into discrete digital values. This can introduce quantization noise, which, although typically lower than analog noise, may become more significant in low-signal environments. Additionally, any noise present in the input signal can be exacerbated during the digital processing stages, particularly if the system is not properly designed to handle it. Overall, while digital receivers can offer advantages like improved signal integrity, they are not immune to noise amplification.
