Band rejection is a phenomenon in waveform signals, where a certain frequency or range of frequencies are lost or removed from a source signal. The term ''band rejection'', when used in electronic signal processing, refers to the deliberate removal of a known frequency range - for instance, to compensate for a known source of interference (such as noise from mains (household) electricity). A specific frequency is removed using a notch filter. In most other senses, band rejection is the unintentional loss of signal caused by imperfections in the recording, storage or reproduction of a waveform. ==See also== *Band-stop filter *Passband *Stopband 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Band rejection」の詳細全文を読む スポンサード リンク
