Digital Signal Processing System Design, Second... < Original >

Design is a constant war against . In the second edition of system design, we move beyond simple algorithms into the harsh reality of hardware:

Every DSP system begins with an act of profound loss. When we sample a continuous wave—a violin’s vibrato or the heat of a star—we are slicing time into discrete moments. The is the guardian of this process; it tells us exactly how much of reality we can throw away without losing its soul. A DSP designer doesn’t just see numbers; they see the "ghosts" (aliasing) that appear when we fail to respect the limits of our own perception. 2.

This is the designer’s balance between cost and clarity. Fixed-point is the grit—efficient and fast, but prone to "noise" and rounding errors. Floating-point is the luxury—vast dynamic range, but demanding more power and space. Design is a constant war against
