Spread spectrum. In telecommunication and radio communication, spread-spectrum techniques are methods by which a signal (e.g., an electrical, electromagnetic, or acoustic signal) generated with a particular bandwidth is deliberately spread in the frequency domain, resulting in a signal with a wider bandwidth.
Lipids are one of the four major groups of organic molecules; the other three being proteins, nucleic acids (DNA), and carbohydrates (sugars). Lipids are made up of the same elements as carbohydrates: carbon, hydrogen, and oxygen.
Lipids are fats or oils, they are formed from Carbon, Hydrogen and Oxygen only. A molecule of fat is made up of an organic acid called 'fatty acid' combined with one molecule â¦ of glycerol. Glycerol = H2-C-O- Stearic acid =H-C-O-Oleic acid =H2-C-O- Palmitic acid hope this is helpful. + 9 others found this useful.
