Class A power amplifier distortion, although low, but its low efficiency and output power is small, so people designed B power amplifier circuit. B amplifier circuit is to work

from the middle point Q moves down to the position Q2, that is static -free base of the transistor bias, b 00 only when the input signal is the role of the transistor is turned on before work. It works when the maximum collector current of the magnitude of the current class Bijia much larger output. But it is only in the positive half cycle of the signal t is not a negative half-cycle work. This causes serious distortion of the output signal o this end, the B push-pull amplifier circuit uses the output of work, consisting of two alternating work tube output, l-140 one of the circuit shown by the NPN transistor VTz and a PNP tube VT3 composition. In the positive half cycle signal VT. 3 work, negative half cycle of the signal VT2 tube in two output tubes, respectively, the output signal of the positive and negative half-cycle, the last in a complete synthesis of the total output of the output signal of the circuit o taken with two different polarities its lack of complementary transistors, so this circuit is called complementary symmetry push-pull output path.
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
