As per your request, I am giving you question paper of the Indian Engineering service’s Electronics and Communication Engineering. hope it helps. Write down Maxwell’s equations for time-varying fields in both the differential and the integral forms. Also write down the word statements of these equations from the mathematical statements in the integral form An SI fiber has NA = 0.173 and supports 400 modes at a wavelength of 1.3u. Calculate its core area. To what value its core area should be reduced so that it is single-mode fiber at .3m? For a 100 km FO link, fibers with 10 km unit lengths and having attenuation loss of 0.4 dB/km are used. Connector which is used between two unit lengths is having 1 dB loss. If the eceiver sensitivity is 10 nW/Mbps, calculate the maximum bit rate so that only one repeateris used in the link. Assume one connector loss at fiber receiver coupling. Power launched onto the fiber is 0 dBm What are the important elements involved in a micro processor based system for the measurement and monitoring of a temperature of a liquid contained in a furnace ? Draw the block diagram for this setup (which should include blocks like transducer, actuator, etc.) and explain the salient features of each of its blocks For more question, I am giving the question papers in attachments. please find.
