Double-sideband suppressed-carrier transmission (DSB-SC) is transmission in which frequencies produced by amplitude modulation (AM) are symmetrically spaced above and below the carrier frequency and the carrier level is reduced to the lowest practical level, ideally being completely suppressed. In the DSB-SC modulation, unlike in AM, the wave carrier is not transmitted; thus, much of the p… WebFeb 9, 2024 · Net Operating Income: Pre-tax amount reflecting gross income less operating expenses, such as cost of goods sold, taxes, rent or lease payments, equipment, …
