A 16-bit A-D-A conversion system for high-fidelity audio research

An A-D and D-A converter system with exceptionally wide dynamic range and low distortion is discussed. The system utilizes 12-bit floating-point approximation at conversion instead of true 16-bit conversion. A deglitching track and hold is illustrated which avoids heterodyning between signal components and the sample clock. Rate-limiting during the transition from hold to track is discussed.
