One method of producing an SSB signal is to remove one of the sidebands via filtering, leaving only either the upper sideband (USB), the sideband with the higher frequency, or less commonly the lower sideband (LSB), the sideband with the lower frequency. Most often, the carrier is reduced or removed entirely (suppressed), being referred to in full as single sideband suppressed carrier (S… WebApr 12, 2024 · The spectra on either side of the carrier impulses are known as sidebands and this type of amplitude modulation is known as double-sideband (DSB) AM. Other forms of AM are double-sideband suppressed carrier (DSB-SC), which is more complex to receive, and single-sideband (SSB). The transmitted AM signal spectrum is shown in Figure 5. opening to dvd goanimate
