Then the conduction angle for this type of amplifier circuit is only 180 o or 50% of the input signal. This pushing and pulling effect of the alternating half cycles by the transistors gives this type of circuit its amusing âpush-pullâ name, but are more generally known as the Class B Amplifier as shown below.
Like Lake Tanganyika, Lake Baikal was formed as an ancient rift valley, having the typical long crescent shape with a surface area of 31,722 km2 (12,248 sq mi). Baikal is home to thousands of species of plants and animals, many of which exist nowhere else in the world.
Although it is commonly believed that Lake Tahoe is of volcanic origin, the Lake Tahoe Basin was actually formed by faultingâfractures in the earthâs crust allowing blocks of land to rise and sink. This occurred over several million years as the Sierra Nevada mountains were rising from a shallow sea.
