Analog signal processing and digital signal processing are considered subfields of the signal processing and DSP applications comprise speech and audio processing, spectral density estimation, radar and various sensor array processing, digital image processing, statistical signal processing, audio coding, video coding, data compression, control systems, seismology, biomedical engineering, signal processing meant for telecommunications, etc. BookMyEssay dedicated experts offer online Digital signal processing case study help in AUS within given deadline.
The Components of DSP
Some components make up a DSP system:
- DSP chip – This is known as the “brain” of a Digital Signal Processing system and all the important algorithms and calculations are done here.
- Input and Output – It is known as the interface to various devices, and particularly, to the physical world. Here, an analog signal is changed to digital. Again, it is processed before converting to the analog domain for interacting with headset users again.
- Program memory – Similar to other memory, this memory of a digital signal processing preserves the programs that are required for data for being translated.
- Memory – It is where DSP algorithms get preserved.
- Data memory – It is the storage space for any info which might require to be processed.
- Computer engine – It is the portion of DSP that computes all the mathematical functions which take place at the time of communication.
Uses of DSP
DSP is commonly used for detecting errors and for filtering and compressing analog signals. This is a kind of signal processing that is performed via a digital signal processor which can execute digital signal processing particularly processing algorithms. Commonly, the job of DSP involves converting analog signals into digital signals before applying signal processing algorithms and processes. For instance, at a time when performed on an audio signal, DSP aids in lessening distortion and noise.
A few applications of DSP comprise digital image processing, audio signal processing, biomedicine, speech recognition, and more.

Benefits of Digital Signal Processing
As the signals become digitized, people get many benefits compared to analog communication like:
- The influence of noise, distortion, and interference happens to be remarkably lesser in a digital signal because they are less affected.
- The implementation of hardware in a digital circuit is more flexible compared to analog.
- Digital circuits tend to be easily designed and inexpensive in comparison to analog circuits.
- Digital circuits tend to be more reliable too.
- The incidence of cross-talk is hardly seen in digital communication.
- Signal processing functions, like compression and encryption, are hired in digital circuits for maintaining information secrecy.
