Question

As the bandwidth of a television camera is increased:

1. more information is gained
2. the vertical resolution is decreased
3. the television camera pick-up tube is allowed to turn on and off more times per second

Answer 1

Increasing the bandwidth of a television camera allows for capturing more information, increasing vertical resolution, and potentially allowing for higher frame rates due to a higher frequency of the camera's pick-up tube activation.

Step-by-step explanation:

When the bandwidth of a television camera is increased, several things can happen:

• More information can be captured due to the ability to transmit a greater range of frequencies, which translates to more visual details in the image.
• The vertical resolution typically increases with bandwidth since the system has the capacity for faster data rates, enabling better picture quality with more lines of resolution defining the vertical detail.
• Increased bandwidth allows for higher frequency signals, which can mean the camera's pick-up tube activates and deactivates more times per second, potentially allowing for higher frame rates and smoother motion capture.

This concept is quite similar to how a telescope with a larger aperture can capture sharper images, as well as how microscopes and optical fibers work to focus light effectively for better resolution.
