The related term "bandpass" is an adjective that describes a type of filter or filtering process; it is frequently confused with "passband", which refers to the actual portion of affected spectrum.

What is the difference between baseband and bandpass?
Bandpass transmission
Baseband transmission is transmission of the encoded signal using its own baseband frequencies i.e. without any shift to higher frequency ranges. Passband transmission is the transmission after shifting the baseband frequencies to some higher frequency range using modulation.
Is passband same as bandwidth?
Passband bandwidth is the difference between the upper and lower cutoff frequencies of, for example, a band-pass filter, a communication channel, or a signal spectrum. Baseband bandwidth applies to a low-pass filter or baseband signal; the bandwidth is equal to its upper cutoff frequency.
What does passband mean?
noun. pass·band ˈpas-ˌband. : a band of frequencies (as in a radio circuit or a light filter) that is transmitted with maximum efficiency.
What is baseband and passband signals?
A baseband bandwidth is equal to the highest frequency of a signal or system, or an upper bound on such frequencies, for example the upper cut-off frequency of a low-pass filter. By contrast, passband bandwidth is the difference between a highest frequency and a nonzero lowest frequency.
