Types of Line Spectrum
There are several types of line spectrum, including:
- AM (Amplitude Modulation): This is the most common type of line spectrum, where the amplitude of the carrier wave is varied to encode information.
- FM (Frequency Modulation): This type of line spectrum uses frequency modulation to encode information, where the frequency of the carrier wave is varied to encode information.
- DS (Direct Sequence): This type of line spectrum uses a direct sequence algorithm to generate the data, which is more efficient than other algorithms.
- CDMA (Code Division Multiple Access): This type of line spectrum uses a code division multiple access algorithm to encode and decode data, which is more efficient than other algorithms.
