What is one common frequency range used in video signaling over coaxial cable?

• A. 1 Hz to 100 MHz
• B. 5 Hz to 1 GHz
• C. 10 KHz to 10 MHz
• D. 100 KHz to 2 GHz

Answer: (B)

The frequency range of 5 Hz to 1 GHz is significant in video signaling over coaxial cable because this range accommodates the frequencies used for various video transmission standards. Coaxial cables are widely employed in television systems and other video communications. Specifically, many analog and digital video signals, including those used in consumer broadcasting and cable systems, typically operate within this frequency range. Utilizing a frequency range that starts as low as 5 Hz allows for the transmission of baseband signals and low-frequency components, while extending up to 1 GHz alongside the ability to carry higher bandwidth signals, including standard broadcast frequencies for television (like those found in channels from 54 MHz up to several hundred MHz). This range is also beneficial for high-definition and digital video signals since such signals can require a broader bandwidth for effective transmission and to maintain video quality. The other options present ranges that do not align as closely with the standards and practical applications observed in coaxial video signaling. For instance, the range of 1 Hz to 100 MHz would be insufficient for many modern video signals that necessitate higher frequencies, while 10 KHz to 10 MHz and 100 KHz to 2 GHz present either too narrow a band or go beyond typical usage patterns for standard
