Correct Ans: (2)
Explanation: Converting a baseband video signal to an RF (radio frequency) signal is known as video modulation. This process involves modulating the video signal onto a carrier frequency, which can then be transmitted over the air or through cable systems. Video modulation is essential in broadcasting and communication systems to ensure that video signals can be effectively transmitted and received over various mediums.
