A specially designed oscilloscope used to graphically display a video signal: (A) Vu Meter (B) Viewfinder (C) Studio Monitor (D) Waveform Monitor Correct Ans: (D) Explanation: A Waveform Monitor is a specialized oscilloscope that is designed to display and analyze a video signal. It helps technicians measure the amplitude, frequency, and phase of video signals. This tool ensures that the video signal meets the required technical standards, such as color balance and brightness. Unlike the VU Meter, which measures audio levels, the Waveform Monitor focuses solely on video signals. The Viewfinder is used for framing and focusing, but it doesn't provide detailed signal information. Similarly, while a Studio Monitor displays video content, it doesn't analyze the signal. The Waveform Monitor allows technicians to identify and correct issues before they affect the final output. This ensures high-quality video for broadcasting or recording. In this way, it helps maintain the technical standards necessary for professional video production. By using the Waveform Monitor, video professionals can deliver content that meets the required technical standards. It is crucial for ensuring high-quality video output.
