synchronization Słowa kluczowe: uchłady PLL, synchronizacja. Introduction The basic phase locked loop (PLL) concept was originally published by Appleton in 1923 and Bellescize in 1932, which was mainly used for synchronous reception of radio signals [1-2]. After that, PLL techniques were widely used in various industrial fields such as communication systems [36], motor control systems [7-8], induction heating power supplies [9] and contactless power supplies [10]. Recently, PLL techniques have

change as an electrical signal, which via software is being graphed. The other end of the catheter is connected to a funnel with a balloon atop and this funnel is junctioned using a 3-way stopcock. The tube is filled with water end to end, the balloon attached on the funnel is blown up which in turn puts pressure on the water which puts pressure on the pressure sensor, that transudes the pressure difference in to an electrical signal and LabView software displays that signal as a graph.

Samer Abboud Signal Processing Final Report 29/5/2014 There are there objectives to this report, as we will see in the three following problems. The first objective is to build a VI to find the magnitude response of each filter while changing the 5 designs of filters(Elliptical, Chebychev, Inverse Chebychev, Butterworth and Bessel) and changing the filter types (Lowpass, Highpass, Bandpass, Bandstop). The second objective which is seen in problem 2 is to generate a pulse with uniform white

in the world. Therefore it is understandable that concepts related to waveforms or signals are extremely important as their applications exist in a broad variety of fields. The processes and ideas related to waveforms play a vital role in different areas of science and technology such as communications, optics, quantum mechanics, aeronautics, image processing to name a few. Even though the physical nature of signals might be completely different in various disciplines, all waveforms follow one fundamental

LTE Initial Access [pic] Like all mobile communication systems, in LTE a terminal must perform certain steps before it can receive or transmit data. These steps can be categorized in cell search and cell selection, derivation of system information, and random access. The complete procedure is known as LTE Initial Access and is shown in the Figure below. After the initial access procedure, the terminal is able to receive and transmit its user data.
