DSP Project Ideas (Digital Signal Processing) And Applications
Digital Signal Processing (DSP) is the manipulation of digital signals to enhance digital communication’s reliability and accuracy.
Physical (analog) signals like audio, video, pressure, temperature, and positions are converted into digital signals using an analog-to-digital converter (ADC).
The digital signals are manipulated and designed for performing mathematical operations like addition, substruction, multiplication, and division.
DSP processes digital signals rapidly, making it popular in industries due to affordable software and hardware.
DSP is used in many applications like image processing, noise reduction, voice enhancement, and speech recognition.
For processing the real-world analog signal, we need an analog-to-digital converter (ADC) and digital-to-analog converter (DAC) at the end of the process.
The flowchart of this process is shown in the figure below.

The main components of DSP are;
- Program Memory: Stores program to process data
- Data Memory: Stores information
- Compute Engine: Processes math operations, accesses program from program memory and data from data memory
- Input/Output: Provides several ports to connect other devices
Why Is It Important to Do DSP Projects (And Not Just Theory)?
DSP has a wide range of applications, and it can be used in appl
