What is the best DSP for what you do?

digital signal processing (DSP) depends on your goals and background.  Why is this?

• DSP includes many different topics, such as:
  • digital filters
  • analysis of signals and systems (especially in terms of frequency)
  • synthesis of signals
  • detection of signals and estimation of signal and system parameters
  • data compression
  • and on and on ...
• DSP is the intersection of a number of different areas of study:
  • mathematics
  • electrical engineering
    • signals and systems
    • analog circuit theory
    • computer architecture, (and more)
  • probability and statistics
  • computer programming
  • and others
• Implementing DSP, especially in real-time, is generally treated separately from the theory, so much so it can seem like a field entirely separate from DSP.
