Full form of DSP is digital signal processor. It is also referred to as Digital signal processing. It is a coprocessor designed specially to perform mathematics in DSP. They are programmable and it means they are useful to manipulate information of different types, including video, images, and sound.
Where is DSP used?
DSP, Digital signal processing is used by specialized digital processors or computers to perform the various operation of signal processing. It involves linear and nonlinear operations. A DSP performs mathematical functions such as subtract, add, divide, and multiply, quickly.
A DSP has key components such as:
- Program Memory. It is this place that the DSP stores the programs that is used for data processing.
- Data Memory. It stores information that has to be processed.
- Compute Engine. The math processing is performed using the Program and Data from the memory.
- Input/Output. The outside world is connected with a range of functions.
What are DSP applications?
DSP applications comprise of audio and speech processing, radar, sonar, and other sensor array processing, data compression, statistical signal processing, spectral density estimation, digital image processing, audio coding, video coding, signal processing for telecommunications, image compression, control systems, and so on.
DSP accuracy level is high. The filters designed have control on the output accuracy in comparison to analogue filters. In an analog system, the reconfiguration is tough as there is a need to change the components and the entire hardware.
DSP is to buy and manage ad inventories using one interface for multiple ad sources. It is normally done using an auction process on the inventories with intelligent software. Thus, it makes selling and buying of ads reliable and cheaper.
Is a DSP must-have?
The cost is $400 plus for processors of good quality. The installation charges are separate. Moreover, it needs an hour to configure the vehicles. For a complex system featuring multi-channel, a DSP is a must-have as it will have lots of input and output channels. It will also need extra time for system configuration.
Information received from a DSP can be used to control things by a computer for telephone, security, video compression, and home theatre systems. The signals can be compressed such that there is the quick transmission and it runs efficiently between places. The signals can be manipulated or enhanced to provide information or improve quality that is not human-sensed such as medical images computer-enhanced or cell phones echo cancellation. The signals in the real-world are processed in analogue form, while digitally processing signals offer a higher advantage of accuracy and speed.
