BD3814FV-E2 is an audio-special-purpose device. It includes many advanced functions to meet the requirements of various home / automotive audio applications. It contains four built-in functions, including independent volume control (IVC), single pulse echo cancel (SPC), noise reduction (NR) and dither generation. The four functions can be used alone or combined to perform some more complex tasks.

Application Field

BD3814FV-E2 can be used in any audio application that requires advanced signal processing functions, especially in home / automotive audio applications. It can work in stereo mode or in mono-channel mode, and its functions can be used to simplify different audio operations, such as reducing background noise, providing accurate audio levels, and so on.

Some of the applications in which BD3814FV-E2 can be used include car entertainment systems, radio receivers, television broadcasting systems, surround sound systems, sound bars and speakers, etc. It is also useful in any other sound systems that require reliable sound output and require advanced signal processing functions.

Working Principle

BD3814FV-E2 is based on a circuit which operates in real-time audio signal processing. It contains four independent functions, that can be used independently or in combination, to perform a variety of audio processing tasks, such as noise reduction, dithering, echo cancellation, etc.

The independent volume control (IVC) function of BD3814FV-E2 allows independent adjustment of the gain and volume levels of a signal. This is especially useful for balanced signals, as it can help prevent signal overload or signal canceling, which can lead to distortion of the audio signal.

The single pulse echo cancellation (SPC) function eliminates echoes in an audio signal. This is especially useful for systems with low-quality speakers, as echoes can cause audio output to be distorted. The SPC operation is based on an FIR filter, and the echo cancellation can be adjusted in real-time, depending on the system’s requirements.

The noise reduction (NR) function of BD3814FV-E2 reduces background noise in an audio signal. This is especially useful in systems which require quality audio output. The NR operation is based on an adaptive digital filter, and the noise reduction can be adjusted in real-time, depending on the system’s requirements.

The dither generation function of BD3814FV-E2 is a special kind of audio noise. It helps to add clarity to digital sound signals, by reducing the possibility of digital audio distortion. The dither generation is based on a random generator and can be adjusted in real-time, depending on the system’s requirements.

In general, BD3814FV-E2 is a useful device for home / automotive audio applications, as it provides reliable audio output and advanced signal processing functions. It can help to improve the audio quality of a system and can also simplify various audio operations.
