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 algae, which are only found in this lake, can actively develop even under the ice. 29. In winter the ice of Lake Baikal develops cracks, which can reach up to 30 kilometers in length and up to 3 meters in width.
