This page talks about the research importance of Digital Signal Processing with its Applications and current DSP Thesis Topics. Digital Signal Processing (DSP) is the sophisticated process for analyzing digital signals to enhance their representation and understanding capability. It is one of the variants of the signal processing field. In general, the acquired or sensed real-world signals are processed in a digital signal processor through particular processing techniques. It not only executes on a digital signal processor but also in other equally capable systems.

Basic DSP Terminology 

• Frequency (Hz) – Number of cycles in a second (1/period)
• Period (s) – one-cycle sine wave completion 
• Amplitude –Distance between origin  and peak height

A few of the DSP applications are digital image processing (DIP), audio signal processing (ASP), biomedical signal processing, digital wireless communication, biomedicine and speech recognition, and more. For instance, In the case of audio signals, DSP assists in reducing the undesired distortion and noise. Here, we have included some DSP systems in day-to-day life applications.

Examples of digital signals

• Radar Signals in Remote Sensing
• Camera Images and Broadcasted Video
• Speech can be recognized in smart phone, radio, TV and more
• Bio-signals are used in medical field  (MRI / CT – brain signals and ECG – heart signals,)

Before we dive into understanding to write up DSP Thesis , Lets first understand DSP Processor. Next, we can see the essential of DSP processors in a real-world application. DSP processor is a specially designed small chip that satisfies all the DSP requirements. It widely works with all sorts of embedded systems to perform DSP operations in real-world signals. Below, we have given the benefits of using a DSP processor.

What is the use of DSP Processor in Real-World Application?

• Efficiency. Efficient in terms of cost, energy efficiency, time and etc.
• Deterministic operation. Prior accurate prediction of program execution time will assure the efficient performance
• Information. The processing of data is required to improve the signal interpretation and eliminate the unwanted signals.
• Flexibility. Accept the customizations, new updates, software modification and more without affecting regular DSP systems performance.
• Maximum throughput. Tolerate large stream data processing in ultra-speed execution. For instance: multimedia application.
• Power. Signals collected from real environment are transformed into another format which support the proposed mathematical models
• Adaptation. The data are dynamically processed where the data can increase or decrease during run-time execution. For instance: industrial application

Top 3 Limitations of DSP

Though DSP has many advantages, it has some limitations in working with complex digital systems. The Top 3 limitations of DSP are speed, finite word length, and bandwidth. Our experts have several unique DSP Thesis ideas to tackle all DSP limitations which affect the performance of the signal and System. Next, we have given the two main benefits that gain the scholar’s attention towards the signal processing field.

• Determine the meaningful data from ambient-noise filled sensed data
  • By means of low computationally intensive techniques
  • Efficient signal processing filtering techniques
• Energy harvesting and saving energy for physical and virtual edge devices

Further, digital signal processing is also used to analyze, filter, measure, and compress analog signals. Since it has add-on unique features such as low processing speed and low power usage, these features make the analog process use DSP for overcoming A/D conversion overheads. In this, DSP clearly removes the chaotic noise in the real-world analog signals for enhancing signal interpretation levels. For your knowledge, here we have given the primary processes involved in DSP.

Major Operations of DSP
