'''Bandlimiting''' is the process of reducing a [[Signal (electronics)|signal]]’s [[spectral density|energy]] outside a specific [[frequency]] range, keeping only the desired part of the signal’s spectrum. This technique is crucial in [[signal processing]] and [[Telecommunications|communications]] to ensure signals stay clear and effective. For example, it helps prevent interference between [[radio frequency]] signals, like those used in radio or TV broadcasts, and reduces [[aliasing]] distortion (a type of error) when converting signals to digital form for [[digital signal processing]].
