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.
It is 5,314 feet deep (1,637 meters) and it's bottom is at 4,215 feet (1,285 meters) below sea level. Lake Baikal is also the world's largest freshwater lake in terms of volume. It is difficult to comprehend how a lake in the middle of a continent could have a bottom that is 4,215 feet below sea level.
