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.
What kind of weather would an occluded front bring? An occluded front would bring colder weather. This type of frontoccurs when a cold front and warm front meet up with one another.The result is the cold air is pushed down.
