Single-Sideband Modulation and Frequency Translation

Part of the Applications of Communications Theory book series (ACTH)


AM and DSBSC-AM modulation do not use the frequency spectrum efficiently. Their spectral components at equal distances above and below the carrier frequency contain identical information, because they are complex conjugates of each other. The portion above the carrier frequency is called the upper sideband and the portion below the lower sideband. In this experiment you will see how a baseband message can be transmitted by using only one of the sidebands and, consequently, half the bandwidth of AM or DSBSC-AM. This type of modulation is called single-sideband (SSB) modulation. It has been used extensively in many radio transmission systems and in the telephone network.
