amplitude limiter circuit的意思|示意

Amplitude limiter circuits are designed to limit the amplitude of a signal, generally the output of an amplifier, to a predetermined level. They are often used in audio systems to prevent loud audio signals from being too loud and causing distortion in the speaker or other components. The limiter can also be used to protect sensitive audio components from being damaged by strong signals.

The amplitude limiter circuit is typically made up of two parts. The first part is a voltage or power limiter, which limits the maximum signal that can be produced. The second part is an output limiter, which restricts the signal’s maximum level. The limiter can be controlled by a number of different methods, including a manual or automatic control.

In audio systems, the amplitude limiter circuit limits the maximum output level of the amplifier, cutting off signals that are too loud. By limiting the maximum level, the amplifier is able to generate a clean, distortion-free sound without causing any damage to the audio components. This ensures that the sound heard is at the desired level, while protecting delicate components.

In addition to audio systems, amplitude limiter circuits are also used in communications and military applications. In these systems, they can help regulate the level of transmission signals, preventing them from exceeding a certain power level and causing interference or damage.

Overall, the use of an amplitude limiter circuit is an effective way to ensure that the signals produced by an amplifier remain clean and distortion-free. By limiting the maximum level, it also helps to protect sensitive audio components from being damaged. The limiter can be manually or automatically controlled, depending on the application.
