The Audibility of Modulation Noise in Floating-Point Conversion Systems
The floating-point conversion technique is particularly suited for digital audio applications where the dynamic range greatly exceeds the signal-to-noise ratio requirement for high signal levels. By adding controlled amounts of noise into the sine-wave and recorded music material, the action of various proposed systems is examined. The effects of preemphasis, various proposed systems is examined. The effects of preemphasis, various gain step sizes, and instantaneous versus near-instantaneous techniques are examined.
