👉 Taintlessness is a concept in the field of information theory, specifically in the context of signal processing and communication. In the context of digital communications, taintlessness refers to the property of an input signal that remains unchanged after any sort of filtering or transformation has occurred on it. In other words, if we have a signal x(t) that is corrupted by noise, then taintlessness means that the output y(t) of the filter (denoted as F) will be identical to x
