Design and Analysis of Pulse -Width Modulation Techniques for Spectrum Shaping
The ultimate goal of spectrum-shaping technology is to provide the designer with the ability to specify a desired harmonic spectrum and then to realize it using a proper modulation scheme. The results of Pd-PWM and FM-PWM bring us one step closer to understanding how to meet this goal.

Spectrum shaping and its application: spread-spectrum clock generator and circuits for ultra wide band
Electromagnetic spectrum can be identified as a resource for the designer, as well as for the manufacturer, from two complementary points of view: first, because it is a good in great demand by many different kind of applications; second, because despite its scarce availability, it may be …

Efficient spectrum sensing and utilization for cognitive radio
… been introduced to opportunistically exploit the spectrum. We present a robust and cost-effective design to ensure the improvement of spectrum efficiency with CR. We first propose probability-based spectrum sensing by utilizing the statistical characteristics of licensed channel occupancy, which …

An Investigation of Active Tonal Spectrum Control as Applied to the Modern Trumpet
… are designed and realized. The farfield spectrum of the trumpet's response to a single note is analyzed for each controller and the resulting attenuations compared. The model of the trumpet system is then used to demonstrate the coupling of the trumpet and the player and to show the …
