What is the approximate bandwidth of a typical single sideband (SSB) voice signal?

• A. 1 kHz
• B. 3 kHz
• C. 5 kHz
• D. 10 kHz

Answer: (B)

A typical single sideband (SSB) voice signal has an approximate bandwidth of 3 kHz. This specification is important because it defines the amount of spectrum that the signal occupies, which is essential for efficient communication and avoiding interference with other signals. SSB is designed to use one of the two sidebands produced in amplitude modulation (AM), effectively eliminating the carrier frequency and one of the sidebands. This results in a more efficient use of bandwidth because SSB signals can transmit voice information using a narrower band than traditional AM, which occupies a bandwidth of about 6 kHz. The 3 kHz bandwidth for SSB is adequate for transmitting the full fidelity of human speech, allowing for clear and intelligible communication. Understanding this bandwidth is crucial for operators, as it helps them to set their transmission equipment properly and to adhere to regulations that govern amateur radio operations.
