Mar-14-11 Human Communication 1 6 Body Language Body language is a form of non-verbal communication, consisting of body pose, gestures, and eye movements. Digital transmission, is the transmitted of digital pulses between two or more points in a communication system. B.2 EYE DIAGRAM OVERVIEW It is called an eye diagram, or eye pattern, because the pattern looks like a series of To be an effective and valuable member of your workplace it is important that you become skilled The rate at which the eye closes as the sampling time is varied (i.e., the slope of the eye-pattern sides) determines the sensitivity of the system to timing errors. In this project eye diagrams were used to obtain information and observe trends under varying system parameters of link length and transmis-sion rate. _____ The study of communication is important, because every administrative function Digital Communication 8 Following are the sections of the digital communication system. The outer fibrous coat— sclera, cornea. Eye Diagram for 1 Gb/s Data Rate Wrap signal back onto itself every 2*T-d seconds Same as an oscilloscope would do Allows immediate assessment of the quality of the signal at the receiver (look at eye opening) 0 0.2 0.4 0.6 0.8 1 1.2 1.4 1.6 1.8 2 x 10−9 −0.05 0 0.05 0.1 0.15 0.2 0.25 0.3 0.35 0.4 Time (seconds) out Eye Diagram what hasn’t been clear until now is how much of an impact ineffective communications has on project outcomes and subsequent business success. The eye diagram can be used to assess the signal quality and to determine possible transmission errors. BER(COM) allows the student to generate and evaluate eye diagrams and investigate the effects of noise, attenuation and dispersion on eye diagrams and BER for the many communication system permutations allowed by The eye diagram is also a common indicator of perfor-mance in digital transmission systems. 3. With no sharing, there is no communication. The following figure shows the image of an eye-pattern. • Eye diagrams are generally calculated empirically – Convolve random data with pulse response of channel – Pulse response is derived by convolving the impulse reponse with the transmitted symbol • For eye diagrams to represent the worst-case, a large set of random data must be used – Low probability of hitting worst case data transitions In addition, a software package was used to estimate Structure of Human Eye: The eye is a hollow, spherical structure measuring about 2.5 cm in diameter. There are many means of communication. to investigate the trends in signal quality by evaluatin g the eye diagrams for the many permutations of system design allowed by ED-COM, and to gain an appreciation of the effects of noise, attenu ation and dispersion on the eye diagrams and the BER Yet, why is it that so many adults with fairly good interpersonal communication skills have long since “unlearned” this fundamental and indispensable nonverbal behavior? Infants instinctually have a strong desire to gaze into others’ eyes. The following is a simplified block diagram of the eye diagram creation process. Makers of digital communications hardware often include eye diagrams in their literature to demonstrate the signal integrity per-formance of their products. This is done by means of an eye diagram measurement. Figure 1.25 General configuration of an eye diagram showing definitions of fundamental measurement parameters. The interior region of the eye pattern is called the eye opening. Communication is the process of transmitting information and common understanding from one person to another.

After a while, assuming a noise-free situation, the eye diagram (i.e. Effective Communication in the Workplace 1 What is Workplace Communication? • Provides More In-depth Understanding of Your Communication Signal Beyond Qualitative Pass/Fail Mask … Humans send and interpret such signals subconsciously. Body language may provide cues as to the attitude or state of mind of a person. The application displays a mask pattern behind the eye-diagram of the commu-nication signal being acquired. Information sources might include audio, video, text, or data. They might be continuous-time (analog) signals (audio, images) and even 1-D or 2-D. Or, they may already be digital (discrete-time, discrete-valued). Eye patterns are a widely used tool for studying the quality and stability of digital communication systems. Fig. In reality, communications are imperfect, so the transitions do not line perfectly on top of each other, and an eye-shaped pattern results.
