The overall radiated pulse shape and frequency distribution are described. Sample calculations are performed to determine the effect of these emissions on a 500 MHz communi cations channel in the 3.7 to 4.2 GHz frequency band. The overall pulse shape can be best described by a decaying exponential. For frequencies greater than 1 kHz the pulse produced a continuous monotonically decreasing frequency distribution which has a slope of 6 dB per octave. The resultant spectral amplitude distribution in the 500 MHz band between 3.7 and 4.2 GHz is nearly flat. The time domain representation of the signal present in the 500 MHz bandwidth between 3.7 and 4.2 GHz is a critically damped exponential pulse with a rise time of 0.37 ns and a fall time on the order of 2.1 ns. Measurements to determine the coupling effects of ignition emissions to a satellite earth station 42-foot full performance antenna are described. The results of these measurements show that the antenna, in its near field, has a very small effective area.","PeriodicalId":296335,"journal":{"name":"IEEE 1976 International Symposium on Electromagnetic Compatibility","volume":"557 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1976-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132939959","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Others have shown that one predominant source of noise interference is conduction of currents in instrument cable shields and building conduits. Since these currents produce noise that is similar to signals produced by nuclear detectors, such noise interference reduces the ability of a reactor instrumentation system to determine the condition of a reactor. Model equations of ground noise interference were derived for a system model consisting of a sensor, coaxial cable, and an amplifier. These equations describe the effect of ground impedance, sensor impedance, transfer impedance, and connector resistance on both low-frequency (less than 100 kHz) and high-frequency (greater than 100 kHz) ground noise interference. Other model equations were derived for a system with a coaxial balun (a flexible coaxial cable wound around a ferrite core) added between the sensor and the sensor amplifier input. Analysis of the model equations reveals the effects of ground noise currents on instrumentation systems and the conditions for minimizing ground interference.","PeriodicalId":296335,"journal":{"name":"IEEE 1976 International Symposium on Electromagnetic Compatibility","volume":"264 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1976-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116395013","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
