In mathematics, the discrete-time Fourier transform (DTFT) is one of the specific forms of Fourier analysis. As such, it transforms one function into another, which is called the frequency domain representation, or simply the "DTFT", of the original function (which is often a function in the time-domain).(This file includes matlab source code about DTFT and also includes explanation report)

NUMERICAL DIFFERENCE APPROXIMATION based on Taylor s expansion---the program give the finite difference coefficient for any number of discrete point. also with that u can differentiate of any function in any order with high accuracy. also u can use it to develop a general finite difference program.

Today, gas turbines are one of the major parts of modern industry. They have played very imported in aeronautical industry, power generation, and main mechanical drivers for large pumps and compressors. This paper proposes to examine the application of fuzzy logic to represent a fuzzy model of a gas turbine and their applications in control systems. The main objective of this work is construction of a fuzzy model of the gas turbine system, the validation results show that this model can be used for the system control and Diagnostics.

In a series of papers in recent years new structures for coherent M-PSK (M-ary Phase Shift Keying) receivers were suggested. These include structures for carrier phase detectors for the carrier PLL (Phase Lock Loop), carrier PLL lock detectors, symbol timing error detectors, symbol synchronization PLL lock detectors, carrier and symbol PLL loop filters, and SNR (Signal to Noise Ratio) estimators
