Howtosignalprocessing
Baseband transmission sends the information signal as it is without modulation (without frequency shifting) while passband transmission shifts the signal to be transmitted in frequency to a higher frequency and then transmits it, where at the receiver the signal is shifted back to its original frequency.

What is baseband modulation?
In baseband modulation the information is formated so that it is represented by digital symbols. Then pulse waveforms are assigned that represent these symbols. These waveform can then be transmitted over a cable. Baseband signals are not appropriate for propagation through many transmission media.
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.
What is the difference between bandpass and passband?
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.
Does baseband use modulation?
Analog baseband FM modulates using frequency modulation. The output is a baseband representation of the modulated signal. The output signal's frequency varies with the input signal's amplitude.
