WebWhen the SNR is low, it isn't easy to achieve clean segmentation. The low SNR segmentation result has background (black) mixed in the object (white) and vice versa. By contrast, the high-SNR image provides clean segmentation with well-defined edges. This is why SNR is important. 3. What are the sources of noise? WebJun 16, 2024 · Use the Signal Strength for a rough idea of direction, but align the antenna for the highest Signal Quality, ignoring Signal Strength. When aimed correctly, Symbol Quality will show 100%, indicating no errors in the output. Splitters and amplifiers can introduce noise which will lower the Signal Quality, even if the Signal Strength increases. other name of ethyne
