In one-way facsimile transmission of weather information, which parameters must be set by the receiving station?

• A. Lines-per-inch (LPI), and primary scan direction (PSD)
• B. Frequency shift (FS), and phase response pattern (PRP)
• C. Black-mode signal (BMS), and frequency jitter tolerance (FJT)
• D. Index of cooperation (IOC), and revolutions per minute (RPM)

Answer: (D)

The correct parameters required to be set by the receiving station in one-way facsimile transmission of weather information are related to how the information is stored and processed. In the context of facsimile (fax) transmission, these specifically pertain to the characteristics of the scanning process used in receiving the image. In one-way facsimile transmissions, especially for weather information, the receiving station must correctly set the lines-per-inch (LPI) to ensure that the image is scanned with the appropriate resolution. The primary scan direction (PSD) is also crucial as it determines the way the image is captured during the transmission process, whether it scans line by line vertically or horizontally. The other options involve technical terms that are not specifically relevant to the process of facsimile transmissions. Parameters like frequency shift, phase response pattern, black-mode signals, frequency jitter tolerance, index of cooperation, and revolutions per minute do not pertain to the facsimile transmission protocol standards. Instead, those options seem to reference other areas of telecommunication or technical specifications unrelated to the basic requirements for facsimile systems. Hence, focusing on the correct lines-per-inch and primary scan direction ensures a proper reception of the weather data transmitted via facsimile.
