3. What is DSP?
• Digital Signal Processing (DSP) is the
mathematical manipulation of an information
signal to modify or improve it in some way. It
encompasses a wide variety of operations that
can be applied to signals, including analysis,
enhancement, compression, and synthesis.
DSP is a key technology in many areas, such as
telecommunications, audio and speech
processing, radar, and biomedical engineering.
4. Historical Background
• The roots of DSP are in the analog signal
processing that was performed in the early
20th century. The transition from analog to
digital processing began with the
development of digital computers and the
formulation of the sampling theorem by
Claude Shannon in the 1940s, which laid the
theoretical foundation for DSP.
