Fuzzy shaper versus leaky bucket shaper in Voice over Internet
Nowadays, is more and more usual to implement the voice service over Internet (VoIP), due to the reduction in price both for the network operator and for the final users. In this paper, it is presented a new traffic shaper that increases the number of stablished connections and minimizes the delay time in the case of using an IP/ADSL (Internet Protocol/Asymmetric Digital Subscriber Line) enviro...
متن کاملCMOS Output Buffer Wave Shaper
Abstract As the switching speeds and densities of Digital CMOS integrated circuits continue to increase, output switching noise becomes more of a problem. This paper reports a novel design technique which aids in the reduction of switching noise. The output driver stage is analyzed through the use of an equivalent RLC circuit. The results of the analysis are used in the design of an output driv...
متن کاملمقایسه تاثیر دو سیستم One-ShapeوXp-endo-Shaperبرمیزان دبری خروجی- مطالعه آزمایشگاهی
خلاصه: سابقه و هدف: خروج دبری از اپکس از عوامل بروز flare up (تورم، درد یا ترکیبی از هر دو) می‌باشد. تحقیقات مختلفی در رابطه با میزان خروج دبری در سیستم‌ها و فایل‌های مختلف صورت گرفته است، ولی تحقیقی در مورد مقایسه دو سیستم One Shape و Xp-endo–Shaper در کانال‌های خمیده گزارش نشده است. بنابراین تحقیق حاضر با هدف تعیین میزان خروج دبری از فورامن اپیکال به دنبال آماده‌سازی با دو سیستم چرخشی One ...
متن کاملA programmable Fresnel transform pulse shaper.
We demonstrate the first reprogrammable Fresnel transform pulse shaper based on a modified direct space-to-time pulse shaping apparatus. In our approach, the pulse shaping lens and mask are implemented by a dual-layer liquid crystal spatial light modulator. The input mask subsequently undergoes a free-space Fresnel transform which causes quadratic dispersion of the output temporal waveform. Whe...
متن کاملModified femtosecond pulse shaper using microlens arrays.
We discuss a modified femtosecond pulse shaper that uses microlens arrays to convert the continuous band of frequencies normally obtained in the mask plane of a pulse shaper into a series of discrete spots. Our experiments demonstrate that this modification can improve pulse-shaping quality when modulator arrays with large interpixel gaps are used for Fourier-plane filtering.
