What type of display technology does the B-scope utilize?

The B-scope utilizes intensity modulation for its display technology. This means that the brightness of the display is adjusted in accordance with the strength of the received signal. In a B-scope, the varying signal intensities are represented visually, with brighter spots indicating stronger signals and dimmer spots representing weaker ones. This allows for effective visualization of information, such as depth and distance, by correlating light intensity to the strength of data being analyzed.

Intensity modulation is particularly beneficial in this context because it allows for immediate visual interpretation of the data, making it easier to understand relationships and changes in signal strength. This is essential in applications like sonar or medical imaging, where the ability to quickly interpret varying signal strengths can lead to more accurate assessments.

Shifting focus to the other possible options, frame-by-frame modulation would imply a different method of displaying information that does not correlate directly with the varying strengths of signals in real-time. Signal-to-noise ratio describes a measurement rather than a display technology, and a pixelated grid typically signifies a digital display format, which doesn't accurately capture the analog nature of the intensity modulation used in a B-scope. Thus, intensity modulation is the method that best describes how the B-scope conveys information visually.
