What is a class amplifier?

often referred to as a digital amplifier is a amplifier Class-D electronic device that increases the size of electrical signals. What distinguishes a class-D amplifier from other types of amplifiers is its design that trades the risk of increased distortion for a very high level of efficiency, allowing it to be smaller and lighter than other amplifiers. Class amplifiers are most often used as speakers amplifiers in audio applications and are particularly popular in situations where the main factor or size of cost or size is. For constant power, it goes to its "collector", while a small signal to the line is fed to its "base". The basic signal controls how much of the collector power passes through the "emitter", a lead from which the amplified signal comes. Clasnavrhy S-A, Class-B and Hybrid Class-AB constantly draws for a collector of energy, whether it needs it or not. This tends to be very ineffective and high amounts of unused force converts into heat that amplifierAlthough it distracts with large and bulky cooling sinks. Class-D amplifier design eliminates most of this inefficiency.

Class amplifiers still use transistors or IC chips, but instead of enlarging the base signal with the collector power supply, they use the base signal to turn on and off the collector. For example, to create a low light light level without a dimmer switch, theoretically the light switch could be switched and off several times per second, causing the eye to register the light that is Dimmer than a fully lit bulb. Class-D amplifiers work on the same principle and when they are "turned off", basically drawing force.

Misnar "Digital Amplifier" is applied to many components of a-D-D-D amplifier because the short pulses they use could come from a digital source. On the other hand, they can also amplify analog signals. In fact, the amplifier designE Class D prevents digital sound technology.

6 Because of this restriction, they first gained popularity in applications such as subwoofer amplifiers, where the type of distortion that created the design was harder to hear. Once the technology has become more refined and the sound quality has improved, they have expanded to cheap consumer sound equipment and portable equipment that required low energy drain to maximize battery life. Until the second decade of the 21st century, class D amplifiers were improved to the extent that they began to be used in professional sound -caplication, as well as in a very top -of -the -art stereo device for audiophile.
