Signal Processing of the High Resolution PEA Charge Measurement System

‏‎design of an analog ram (aram)chip with 10-bit resolution and low-power for signal processing in 0/5m cmos process‎‏

برای پردازش سیگنال آنالوگ در شبکه های عصبی ، معمولا نیاز به یک واحد حافظه آنالوگ احساس میشود که بدون احتیاج به ‏‎a/d‎‏ و‏‎d/a‎‏ بتواند بطور قابل انعطاف و مطمئن اطلاعات آنالوگ را در خود ذخیره کند. این واحد حافظه باید دارای دقت کافی ، سرعت بالا ، توان تلفاتی کم و سایز کوچک باشد و همچنین اطلاعات را برای زمان کافی در خود نگهدارد. برای پیاده سازی سیستمی که همه این قابلیتها را در خود داشته باشد، کوشش...

Three novel high-resolution nonlinear methods for fast signal processing

Three novel nonlinear parameter estimators are devised and implemented for accurate and fast processing of experimentally measured or theoretically generated time signals of arbitrary length. The new techniques can also be used as powerful tools for diagonalization of large matrices that are customarily encountered in quantum chemistry and elsewhere. The key to the success and the common denomi...

High-Precision Frequency Measurement Using Digital Signal Processing

High-precision frequency measurement techniques are important in any branch of science and technology such as radio astronomy, high-speed digital communications, and highprecision time synchronization. At present, the frequency stability of some of atomic oscillators is approximately 1E-16 at 1 second and there is no sufficient instrument to measure it (C. A. Greenhall, 2007). Kinds of oscillat...

6 High - Precision Frequency Measurement Using Digital Signal Processing

Parallel Signal Processing System for a Super High-Resolution Digital Camera

The technology of the digital still camera has recently achieved remarkable progress. The number of pixels in the main stream of consumer-use cameras has reached the 3 million-range, with 5 million the maximum. And for professional-use, the number of pixels has reached the 16 million. Digital still cameras convert signal data generated from these pixel CCD's to luminosity signals and chromatici...
