What is baseband spectrum?

A baseband signal is one that has a frequency spectrum which begins at 0Hz (DC) extending up to some maximum frequency. Though a baseband signal includes 0Hz, the magnitude at 0Hz may be 0 (i.e., no DC component).

What frequencies are used in baseband communication?

In a baseband communications link, frequencies upto 3500 Hz are used for signaling.

What is baseband signal in communication?

A baseband signal or lowpass signal is a signal that can include frequencies that are very near zero, by comparison with its highest frequency (for example, a sound waveform can be considered as a baseband signal, whereas a radio signal or any other modulated signal is not).

Which signal does baseband network uses?

The baseband transmission utilizes digital signalling for signal transmission. In contrast, broadband transmission utilizes analog signalling for transmitting analog signals.
