In the Senate of the United States. April 28, 1858. -- Ordered to be printed. Mr. Mason made the following report. (To accompany Joint Resolution S. 33.) The Committee on Foreign Relations, to whom was referred the letter of the Secretary of the Navy of the 21st inst., and the correspondence accompanying it, containing information of the condition of the United States ship Susquehanna on her late arrival at Port Royal, in the island of Jamaica, having the yellow fever on board, and of the reception and assistance extended to the officers and crew by the British naval authorities of that island, communicated to the Senate pursuant to their resolution of the 19th April, have had the same under consideration, and now report |

Sommario/riassunto |
|
In recent years the protection of communication services operating in the same of adjacent channels has become more and more challenging. Communication systems need to be protected from natural and man-made interference. This practical reference provides a thorough understanding of how to protect communication systems from intentional and unintentional electromagnetic interference. Engineers learn how to overcome critical problems in both digital and analog communications. This unique resource shows how to shield equipment from electrical and magnetic fields, design TEM and GTEM-Cell, build capacitive coupling clamps for susceptibility tests, protect electronic equipment with filters, and calculate the measurement uncertainty. Professionals find numerous, well-illustrated examples that make challenging electromagnetics issues far easier to comprehend. CD-ROM Included! Contains time-saving software that helps engineers perform important calculations, including characteristic impedance of TEM-Cell, cut-off frequencies for higher order modes, and cut-off and resonant frequencies for GTEM-cell. |
