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.
And only on Lake Baikal gas hydrates were found at a shallow depth and in a freshwater reservoir. 7. Lake Baikal is the oldest lake in the world; it is about 35 million years old (according to other sources â 25 million years old). Usually freshwater lakes quickly get âovergrownâ with silt, sometimes even in a matter of a few decades â and thus disappear.
