Passband - Wikipedia, the free encyclopedia

日期：2024-07-15

A passband is the range of frequencies or wavelengths that can pass through a filter without being attenuated. A bandpass-filtered signal (that is, a signal with energy only in a passband), is known as a bandpass signal, contrary to a baseband signal.[1]...
