A new iterative WLS Chebyshev approximation method for the design of two-dimensional FIR digital filters

In this paper, based on Chi-Chiou’s weighted least-squares (WLS) Chebyshev approximation method which is for the design of one-dimensional (1-D) FIR digital filters with arbitrary complex frequency response, we propose a new iterative W L S Chebyshev approximation method for the design of two-dimensional (2-D) FIR digital Alters with arbitrary complex frequency response. Several design examples...

Design of Digital Filters Using Genetic Algorithms †

In recent years, genetic algorithms began to be used in many disciplines such as pattern recognition, robotics, biology, and medicine to name just a few. These optimization algorithms are based on Darwins principle of natural selection which happens to be a slow process and, as a result, these algorithms tend to require a large amount of computation. However, they offer certain advantages as we...

tight frame approximation for multi-frames and super-frames

در این پایان نامه یک مولد برای چند قاب یا ابر قاب تولید شده تحت عمل نمایش یکانی تصویر برای گروه های شمارش پذیر گسسته بررسی خواهد شد. مثال هایی از این قاب ها چند قاب های گابور، ابرقاب های گابور و قاب هایی برای زیرفضاهای انتقال پایاست. نشان می دهیم که مولد چند قاب تنک نرمال شده (ابرقاب) یکتا وجود دارد به طوری که مینیمم فاصله را از ان دارد. همچنین مسایل مشابه برای قاب های دوگان مطرح شده و برخی ...

Approximation of ECG Signals using Chebyshev Polynomials

The ECG (Electrocardiogram) signal represents electrical activity of heart and is recorded for monitoring and diagnostic purpose. These signals are corrupted by artifacts during acquisition and transmission predominantly by high frequency noise due to power line interference, electrode movements, etc. Addition of these noise change the amplitude and shape of the ECG signal which affect accurate...
