In a baseband transmission, the entire bandwidth of the cable is consumed by a single signal. In broadband transmission, signals are sent on multiple frequencies, allowing multiple signals to be sent simultaneously.

Also

Baseband Signalling:

1)Uses digital signalling

2)No frequency-division multiplexing

3)Bi-directional transmission

4)Signal travels over short distances

Broadband Signalling:

1)Uses analog signalling

2)Unidirectional transmission

3)Frequency-division multiplexing is possible

4)Signal can travel over long distances before being attenuated
