What is a digital signal processor?

The digital signal processor is a special computer program that uses digital calculations and possibly one or more analog inputs to generate the required analog outputs. For example, a voice converter can accept a normal voice from the microphone. This normal voice becomes a stream of digital bytes or words that can be digitized to create a "different" voice. It is also located in audio cards of personal computers (PCS) and laptops. The development of digital signal processors promises new products that change the way people live. Technology such as voice recognition and biometric recognition is made possible thanks to digital signal processing systems.

Due to the superiority of the digital signal processor and the declining cost of digital hardware, digital signals have become a powerful technology for creating better products for E.NTAainment and communication. Digital TV signal (TV) that reaches home shows a new capacity of two -way digital signalingwhere domestic viewers can actually communicate with TV broadcasting devices in different ways. One of them is video on request and pay-per-view. The A/D converter converts an analog to the digital and digital analog converter (D/A) converts digital to analog. For example, the A/D converter output can be stored as a binary file on a computer or laptop.

The

digital signal processor has a digital processing unit that can receive machine instructions belonging to this computer program Operation-Plus-Argument. For example, a numeric code, such as 9E, can create a machine sequence that converts the 8 -bit registry content to the adigital port cascading into a digital converter into an analog converter. The digital processing unit can perform almost any type of digital calculation.

There are many interesting applications for digital signal processor. When the noise is reduced canto be the aim of eliminating sound noise that is repeated regularly or periodic, such as engine or engine noise. The digital signal processor can detect the noise it converts into digital. Due to digital data and expected time delay, the digital signal processor "off the phase" of Canceller as digital words that will be fed to the built -in D/A converter to control the analog speaker for noise. The resulting noise level is significantly reduced because this computer program also monitors the resulting noise level and performs digital adjustments to compensate for minimal noise.
