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.
Baikal is a rift lake in the south of Siberia which contains roughly 20% of the world's unfrozen surface freshwater â the greatest in the world by volume. It is 1,642 meters deep and among the clearest of all lakes. At 25 million years old, it is also thought to be the world's oldest lake.
