To take into account the loss in the cable, we just have to deduce the 3 dB loss from the 18 dBi gain and use a modified antenna gain of G = 15 dBi. In one click we find the electrical field strength E = 1.4 V/m, the magnetic field strength H = 3.7 mA/m and the power density S = 5.0 mW/m2.
Types of Data: Primary and Secondary data. There are many ways of classifying data. A common classification is based upon who collected the data. Primary data: Data collected by the investigator himself/ herself for a specific purpose. Examples: Data collected by a student for his/her thesis or research project. (In movies) The hero is directly told by the heroine that he is her âideal manâ.
Primary Sources are the first hand evidence left behind by participants or observers at the time of events. Secondary Sources are materials that digest, analyze, evaluate and interpret information contained within primary sources or other secondary sources. Autobiographies, memoirs, diaries, emails, oral histories.
