Amplitude and Frequency/Phase Modulation
I always had difficulties in understanding frequency modulation (FM) and its frequency spectrum. Even for the pure tone modulation, the FM spectrum consists of an infinite number of sidebands whose signs change from one sideband to the next one and whose amplitudes are given by the horrible Bessel functions. . . I work for Zurich Instruments, a Swiss maker of lock-in amplifiers and it has becom...
متن کاملA Compact , Agile , Low - Phase - Noise Frequency Source with Am , Fm and Pulse Modulation Capabilities
This paper presents a broadband frequency source featuring high technical characteristics and extended functionality. The source is a compact (5 by 7 by 1 inches) module that covers the 0.1-to-10 GHz frequency range with a 0.001 Hz step size. The module is based on a novel (patent pending) PLL design that combines fast switching speed, low phase noise, and low spurious characteristics. The meas...
متن کاملAmplitude and Phase Modulation Using QAM Receivers
Simulations have investigated single laser 100G Ethernet links enabled by CAP-16 using QAM receivers that not only lower significantly system timing jitter sensitivity but also outperform PAM and standard CAP in terms of power margin. OCIS codes: (060.2330) Fiber optics communications; (060.4080) Modulation.
متن کامل8 Phase - Shifting Interferometry by Amplitude Modulation
In optics, the superposition of two or more light beams at any point over space can produce the apparition of interference fringes. When these fringes are applied to resolve a problem in industry or they are related with some property of an investigation matter of interest in some area of physics, chemistry, biology, etc., the evaluation of them is a very necessary task. One of the most used me...
متن کاملsynthesis of platinum nanostructures in two phase system
چکیده پلاتین، فلزی نجیب، پایدار و گران قیمت با خاصیت کاتالیزوری زیاد است که کاربرد های صنعتی فراوانی دارد. کمپلکس های پلاتین(ii) به عنوان دارو های ضد سرطان شناخته شدند و در شیمی درمانی بیماران سرطانی کاربرد دارند. خاصیت کاتالیزوری و عملکرد گزینشی پلاتین مستقیماً به اندازه و- شکل ماده ی پلاتینی بستگی دارد. بعضی از نانو ذرات فلزی در سطح مشترک مایع- مایع سنتز شده اند، اما نانو ساختار های پلاتین ب...
