the properties of the metal. So for example take two objects A and B made of aluminium. Both are of a different size. The resistance of A & B will be different. But the resistivity will be the same. Why do we need modulation and carrier wave? In simple terms‚ modulation is required to transmit signals from variuos sources simultaneously over a common channel by means of ’multiplexing’.For ex.‚ the bandwidth of speech signals is 3.3KHz.‚and transmitting N no.of speech signals simultaneously

Jose J Campos May 25‚ 2015 CMGT 554 Communication Media Communication media refers to the means of delivering and receiving data or information. The communication media acts as a communication channel for linking various computing devices so that they may interact with each other. Below is a chart that shows the different types of communication media. Analog and Digital Data Transmission There are a number of differences between analog and digital transmission‚ and it is important to understand

material used to introduce the gene‚ usually a plasmid or bacteriophage‚ is called the vector. Ideal vectors have high rates of replication. Gene cloning is an important procedure in genetic engineering that allows us to produce a large amount of a useful gene product: for instance‚ insulin can be made for diabetic individuals by cloning genes from pancreatic cells.(Wikipedia 15/11/2014) Cloning vector: A cloning vector is a small piece of DNA‚ taken from a virus‚ a plasmid‚ or the cell of a higher organism

Vectors Lab Report ABSTRACT: This lab was about constructing vectors graphically and being able to find the resultant of the vectors. Using a ruler to make the vectors and solving them graphically to find the resultants. INTRODUCTION: This lab was important because it went into higher depth on graphically creating vectors and being able to find the resultants. The structures of these vectors have right angles and have combinations that can look the same‚ yet the angles are going different

CS3282 Digital Comms 9.1 2 May’06 / BMGC Multi-level digital modulation & demodulation. 9.1. Introduction: So far‚ in looking at carrier modulated data transmission‚ we have concentrated mainly on binary signalling using simple forms of ASK‚ FSK and PSK. With a suitable pulse-shape‚ binary signalling can achieve a bandwidth efficiency of up to 2 bits/second per Hz using real unipolar pulses (base-band equivalent of ASK) or real bipolar pulses (base-band equivalent of PSK) at base-band.

Waveguides - A system of material boundaries in the form of a solid dielectric rod or dielectric-filled tubular conductor capable of guiding high-frequency electromagnetic waves. FTTH – Fiber-to-the-home the fiber reaches the boundary of the living space‚ such as a box on the outside wall of a home in order to provide electronic connection. Simplex – Of or relating to a telecommunications system in which only one message can be sent in either direction at one time. Half – Duplex – Half duplex communication

excessive spending that the president was responsible for was noticed as a problem but no action was taken. The board members also voiced concern about the over exaggerated “fraudulent” business plan that President Wiegart was using to raise money for Vector. Wiegart was not only losing the trust of his board members and employees but also his potential investors. Another problem‚ not mentioned in the case‚ was the board members themselves. They were all selected by the founder and president of the
