ETM2126: INFORMATION THEORY & ERROR CODING Tutorial 2 Tutorial 2: Channel Capacity 1. Two identical binary symmetric channels with transition probability p are connected in cascade. i) Draw the original channel diagram. ii) Find the overall channel matrix of the resultant channel and then draw the equivalent channel diagram. 2. Find the value of conditional entropy for a noiseless binary channel. 3. A telephone line channel has a bandwidth of 3 kHz and a S/N

The ears are one of the most complex and interesting systems thats human body has and the sounds we hear are actually in many different parts deflected‚ absorbed‚ and also filtered by our different body parts. It’s then collected by our pinnae (the external part of or ears)‚ whose dimensions further affect the sound on its way into ear. There‚ vibrations are translated into signals‚ which are interpreted by your brain. In the 1930s‚ two scientists at Bell Labs‚ Harvey Fletcher and Wilden A. Munson

Ultrasound Ultrasound is an imaging technique that uses high frequency sound wave and echoes. There are different kinds of ultrasound they are two-dimensional image‚ 3D ultrasound imagining‚ and Doppler ultrasound. Doppler ultrasound is based on the Doppler effect. (Doppler effect is whenever relative motion exists between a source of sound and a listener and the frequency of the sound heard by the listener sounds different compared to the frequency when there is no motion.) The frequency of the

CHAPTER 1 INTRODUCTION 1.1 Background Design of Experiment (DOE) was developed in early 1920’s by Sir Ronald Fisher at the Rothamsted Agriculture Field Research Station in London‚ England. DOE can be used to observe how the design factor or parameters affect the performances. DOE also used to planning‚ designing and analyzing the experiment so that the objectives can be achieved and obtain effective results. The use of DOE in experiment reduce the time and effort with the availability of modern simulation

ACCIDENT IDENTIFICATION USING RF AIM: The aim of this project is to implement an accident identification system wirelessly using one of the wireless communications Radio Frequency. DESCRIPTION: Generally we don’t have any information while our closest friends or family members met an accident at some distance. Due to that we may face severe situations at sometime. To avoid this problem we are using accident identification system using RF‚ by this we get the intimation
