Single-sideband AM radio systems are used to transmit information by using the spectrum in a more efficient manner than that of FM systems. Where FM equipment transmits information using two sidebands around the carrier that on the average require appreciable power for the carrier itself, SSB not only uses just one sideband but also the carrier

• AM single-sideband suppressed carrier (SSBSC) is a form of amplitude modulation in which the carrier is totally suppressed and one of the sidebands removed. • The frequency spectrum and relative power distribution for SSBSC with upper sideband transmission are shown in Figure 6-lc.
single-sideband system. Radio transmission with supressed carrier and a single sideband has been used almost as long as the con-ventional double-sideband amplitude – modulated type. It was employed for transatlantic radiotelephony at low frequencies as long ago as the early nineteen twenties. Because at that time the direct filter method was the
CHAPTER 6 SINGLE – SIDEBAND COMMUNICATIONS SYSTEMS # DEFINITIONS TERMS 1) A form of amplitude modulation in which the carrier is transmitted at full power but only one of the sidebands is transmitted. AM Single-sideband Full Carrier ( SSBFC ) 2) A form of amplitude modulation in which the carrier is totally suppressed and one of the sidebands
The simplest system that implements SSC-SC modulation is the Hartley modulator [1, 2], shown in Figure 3.1.1. This circuit results in single-sideband ( SSB) modulation or more precisely single-sideband modulation suppressed-carrier ( SSB-SC) modulation.
This new edition of the classic single sideband (SSB) reference, first published in 1987, features two entireley new chapters and updated sections throughout. New topics covered include the use of computer algorithms in SSB design, new hardware and software developments, and case studies of new, state-of-the-art SSB systems. • In the “single-sideband, pilot carrier” system only one sideband is transmitted, but a low-level car-rier of sufficient amplitude for re-ception is also transmitted. To demodulate this signal, the pilot carrier is separated from the side-band in the receiver, then ampli-fied and used as the conversion frequency to demodulate the side
This vector diagram illustrates how 50-watt single-sideband signal yields 70% (3 db.) less audio voltage upon detection than a double-sideband signal with 25 watts in each sideband see Figure l-l-C.Fig.a. increase our single-sideband maximum power which gives us a power gain of 4 over the double-sideband condition.
An SSB transmitter is simply the SSB receiver in reverse. Filters and modern double-balanced frequency mixers work in both directions. Amplifiers are wired in such a way to relays or PiN didoes so

Chapter 3: Single-Sideband (SSB) Communication Systems BENT 3753: Communication Principles 39 Chapter 3: Single-Sideband (SSB) Communication Systems Conventional AM DSB communications systems have two inherent disadvantages. First, with conventional AM, carrier power constitutes two-thirds or more of the total transmitted power. This is a major drawback because the carrier contains no information.
