This paper proposes the use of band-limited random sequences to introduce further flexibility in the spread spectrum based audio data hiding. To realize the sub-band data hiding, a systematic method is developed in order to generate band-limited and orthonormal random sequences of any length. In experiments, we evaluated the selective use of frequency(More)
A symbolic layout system for double-metal silicon-gate MOS technology in the style of Gate Matrix is presented. This system provides an integrated layout environment which consists of stick-figure-based graphic editor, a mask artwork generator, a connectivity checker, a circuit parameter extracter and simulator interfaces. All the modules are designed to(More)
