Following are the difference between baseband transmission and 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.
