For M = 1 (i.e., 100% modulation), the envelope of the modulated signal periodically reaches zero, and the sidebands are 6 dB below the carrier. For smaller M, the sidebands are lower (smaller) than that(i.e., by more than 6 dB). For very small , most of the transmitter power is used for the M chrysler sussex

WebCircuits and methods are described herein for suppressing interference in binary offset carrier (BOC) modulated signals The BOC signal includes an upper sideband (USB) and a lower sideband (LSB). The LSB or the USB of the BOC signal is rotated from a first frequency to a second frequency. Interference in the rotated LSB or USB is reduced. An output BOC … 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.
