What is Digital Signal Processing (DSP) ?

Digital Signal Processing (DSP) is the manipulation of signals in digital form, encompassing the conversion, processing, and reconstruction of signals for various applications. It involves:

• Conversion: Converting analog signals to digital form for processing.
• Processing: Filtering, compressing, and manipulating digital signals.
• Signal Reconstruction: Converting processed digital signals back to analog form, if necessary.

Applications of DSP include audio and speech processing, image and video processing, telecommunications, and biomedical signal processing, offering advantages such as flexibility, accuracy, and efficiency. DSP is foundational in developing advanced technology across various fields.
