Following are the difference between baseband transmission and bandpass transmission
| Baseband transmission | Bandpass transmission |
|---|---|
| The baseband transmission does not use modulator and demodulator. | It is used modulator and demodulator. |
| 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. |
| If the baseband signal is transmitted directly then it is known as baseband transmission. | If modulated signal is transmission over the channel, it is known as bandpass transmission. |
| It is prefer at low frequencies. | It has fixed band of frequencies around carrier frequency. |
| It is used for short distances. | It is used for long distances. |
| More noise as signal is original. | Less noise as signals is modulated. |
| E.g. general telephony. | E.g. AM & FM. |
