PULSE MODULATION TECHNIQUES INTRODUCTION • Modulation is the process of frequency translation in which any one parameter(Amplitude‚ frequency or phase) of high frequency carrier signal is varied in accordance with instantaneous value of low frequency modulating signal. • Modulation is either analog or digital. INTRODUCTION • Many signals in modern communication systems are digital • Additionally‚ analog signals are transmitted digitally • Digitizing a signal results in reduced distortion

Addition of Force Vectors Abstract The purpose‚ of this experiment‚ was to prove that there is a relation between the magnitude of the resulting vector‚ and the angle between the vectors that are being added. The test was performed by creating a balance between three weights tied to strings on a pulley that transferred the string on top of a graduated disc‚ which made easy the measurement of the angles between them. After performing the experiment‚ my group concluded that there is a relation

How Disease is Spread by Vectors In medical science or biology‚ a vector refers to an agent (microbes‚ animals or person) that does not cause disease by itself but helps in transmitting the pathogens that cause disease from one host to another. In this sense‚ the host could be humans‚ animals or plants. These vectors have contributed to the epidemic of so many diseases. Different diseases are transmitted by different vectors but some ailments share common vectors. For instance female anopheles

Modulation Techniques Modulation Techniques Modulation is the process in which a signal is entered into and transmitted by a signal carrier. There are several ways signals can be modulated and differ based on the equipment and technique utilized. Three common ways that signals are transmitted include a 56K modem‚ an asymmetrical digital subscriber line (ADSL)‚ and Wireless Fidelity (Wi-Fi). Each of these methods are effective means of transmitting a digital signal‚ however‚ the 56K modem is all

1.1 Development of Windows 95 a) Personal computers (PC) are developed from the 8-bits Apple in 1976 to the 16-bits PC/AT/XT in the 80¡¦s‚ then to the 32-bits 386/486/586/Pentium today. b) In the past‚ MS-DOS‚ a 16-bits operating system (OS)‚ dominates the OS for PCs. For those 32-bits computers i.e. 386/486/586/Pentium‚ processing speed are reduced because of under-utilize of the other 16-bits. c) Besides slow in processing speed‚ the usable memory of DOS is limited to 640K. This cause computer

Vector aeromotive corporation case study Vector Aeromotive Corporation was a company which designed‚ manufactured and sold exotic sports cars. Vector was the only U.S.-based manufacture of exotic sports cars‚ and his major competitors were Ferrari and Lamborghini. Gerry Wiegert is the President and founder of this company. In 1987‚ the board of directors was formed with three directors. This case shows events happening between the board and President Gerry. In March 1993‚ the company’s financial

Besides‚ the cognitivism studies the human mind‚ thoughts and mental processes and states connected with them. The problematic area of the modern cognitive linguistic is rather wide. [24; 35] We decided that it would be interesting to investigate the basic notion of cognitive linguistics on the basis of W.S. Maugham’s novel “Theatre“. W.S. Maugham’s early reputation was based on his comedies of manners for the stage. Among the best remembered of his witty‚ cynical and frankly commercial plays are
