What is the spectrum of a baseband signal?
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 is spectrum in digital signal?
The signal spectrum describes a signal's magnitude and phase characteristics as a function of frequency. The system spectrum describes how the system changes signal magnitude and phase as a function of frequency. For example, Figure 6.6 shows the magnitude and phase spectra of some hypothetical system.
What is the frequency range of baseband signal?
In the Fourier Domain, a baseband signal is a signal that occupies the frequency range from 0 Hz up to a certain cutoff. It is called the baseband because it occupies the base, or the lowest range of the spectrum.
What is baseband transmission of a digital signal?
Baseband transmission systems transfer digital signals in the form of a train of pulses. Signals transferred in baseband systems are not moved from their original frequency bands as no sinusoidal carrier modulation is used.
