Thermal noise occurs in all transmission media and communication equipment, including passive devices. It arises from random electron motion and is characterized by a uniform distribution of energy over the frequency spectrum with a Gaussian distribution of levels.
An occluded front is formed when a cold front overtakes a warm front. and usually form around mature low-pressure areas. The cold and warm fronts curve naturally poleward into the point of occlusion, which is also known as the triple point.
front brings gentle rain or light snow, followed by warmer, milder weather. Stationary front Forms when warm and cold air meet and neither air mass has the force to move the other. They remain stationary, or âstanding still.â Where the warm and cold air meet, clouds and fog form, and it may rain or snow. Can bring many days of clouds and precipi-tation.
