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.
