ADR-003: Dual structure (basics + topics)

Status

Accepted

Context

The material serves two audiences: students learning DSP fundamentals, and practitioners/portfolio visitors interested in specific techniques. A single structure forces a compromise on tone and depth.

Decision

Split into two sections: - basics/: Sequential learning path (chapters build on each other). Pedagogical tone: build intuition, work through examples. - topics/: Standalone reference pages (read in any order). Research-flavored: honest about open questions and limitations.

Consequences

• Positive: Each section can use the tone appropriate to its audience without compromise.
• Positive: Topics can reference basics for prerequisites without repeating them.
• Negative: Some overlap between basics (e.g., filter design) and topics (e.g., biquad filters). Managed by cross-referencing rather than duplicating.
