Discrete semiconductors are individual circuit components that are designed to perform single functions in electric circuits. The construction and functionality of a discrete semiconductor will have a direct impact on the electric current that is flowing through the circuit. Unlike integrated circuits that contain numerous semiconductors that work together to achieve specific goals, discrete semiconductors are designed to work as individual components.
There are different types of discrete semiconductors that are widely used in audio and video applications. Diodes and transistors are just among the most popular types. Each type is designed to perform a single specific role in an application or a device. When buying discrete semiconductors for audio and video applications, you first need to know the role that it will play in your application. In this article, we are going to discuss in detail the various roles of discrete semiconductors in audio and video applications.
Discrete semiconductors are used for converting signals from one form to another in audio and visual applications. In most cases, it is usually the conversion of signals from analog to digital forms though there are cases when the signals have to be converted from digital to analog forms.
For the audio signals, they have to be played in speakers and even amplifiers. Digital-to-analog converters are used for converting digital audio files into analog formats that can be processed and played in the speakers. When it comes to audio recording systems, the reverse is true whereby raw analog signals have to be converted into digital format for storage.
Signal converters have different discrete semiconductors that facilitate smooth and efficient signal conversion which will be important in the processing, transmission, and storage of signals. Transistors are among the discrete components that are widely used in signal converters.
Devices and appliances that are used in audio and video applications have signal processors. Signal in its raw form will not be relevant. It has to be processed so that meaningful audio and visual data can be extracted. Signal processing encompasses an array of activities such as modulation, demodulation, filtering, and even mixing. All these processing tasks are executed by specialized digital signal processors, which are made of discrete semiconductors.
Semiconductors that are present in digital signal processors have the full capacity to manipulate the signals so that you get the desired results. The quality output signal that you get from an audio system is due to the presence of signal processors.
Modern audio and digital devices and advanced control features allow users to do further manipulation of the signals.
Used on display technology
Display is an important element in the video application. The video files have to be displayed on a display unit. Some audio devices also have a display system on which media files should be displayed. Discrete semiconductors are widely used in the running and operation of the display technology.
Name any modern display technology that is used on video applications and you will not fail to identify the presence of discrete semiconductors. LED is among the basic display technology and under it we have OLED. All of them are derived from the working principle of diodes. As a discrete semiconductor, a diode is able to determine the output of the current that will eventually determine the production of images on the display unit.
User interface of audio and video systems
All devices that are used in the audio and video applications have a user interface. The only thing that differentiates them is the level of sophistication. Some have basic features while others are quite sophisticated. Otherwise, all of them rely on discrete semiconductors to operate.
The primary role of the user interface is to determine the output of audio and video. You can determine the sound and video that should come from the device. The operation of some user interfaces entails regulating the flow of current into different components. This is a task that is executed by different semiconductor components.
Advanced control modules of video and audio devices have sensors that are able to capture data and instructions that will determine the output from the device.
Supporting connectivity between different audio and video devices
Discrete semiconductors are the backbone of the interconnectivity between different devices that are used in audio and video applications. Whether the connection is wired or wireless, semiconductor components will always play vital roles in facilitating these connections. They provide an interface between one device with another.
Discrete semiconductors are also widely used in supporting wireless technologies such as WIFI and Bluetooth. This way, different audio and visual devices can be connected remotely.
Power management in audio and video devices
Since devices and audio and video applications use power, there is need for proper power management. Discrete semiconductors regulate the flow of current to different components in audio and video devices. They also ensure that each component gets the right amount of current and voltage.
Choosing the right discrete semiconductor for audio and video applications
Now you know all the essentials of discrete semiconductors in audio and video applications. So, what type of semiconductor component would you like to buy and use in the application? As we have already stated, the first step entails defining the specific function of the semiconductor. What will it do in your audio or video application?
Once you have known the function, you can proceed to address the technical parameters of the discrete semiconductors. They include the rated current, voltage, and frequency among others. These specifications will determine the compatibility and suitability of the discrete semiconductors in the application.
Once you have covered all the technical factors and parameters, you can now focus on where to buy discrete semiconductors for audio and video applications. You should definitely focus on the best manufacturers and suppliers of discrete semiconductor components. Since finding such manufacturers can be quite a hectic task or process, the alternative route is using an electronic components sourcing agent. They will source the right discrete semiconductor components from the best manufacturers, suppliers, and distributors in China.
