Um método de previsão de perturbações na recepção do sinal de TV foi desenvolvido a fim de elaborar contramedidas para interferências causadas por emissões indesejadas de equipamentos de tecnologia da informação (ITE). Os parâmetros de previsão foram determinados medindo os níveis de emissão do ITE em um local de teste aberto, as características de propagação das emissões indesejadas do ITE em um edifício, a potência de saída da estação transmissora de TV, as características de propagação das ondas de rádio da TV e a diretividade. da antena receptora de TV. Foi prevista a possibilidade de ocorrência de perturbações na área de Kanto e os resultados mostram que, no pior dos casos, surgirão perturbações em cerca de 11% das áreas num raio de 30 m de um edifício que contenha tais equipamentos. Isto também mostra que a perturbação pode ser suprimida melhorando a blindagem do equipamento ou do edifício em apenas 10 dB.

Abstract: A method of predicting disturbances to TV signal reception has been developed in order to workout countermeasures for interference caused by unwanted emissions from information technology equipment (ITE). The prediction parameters were determined by measuring the emission levels from ITE at an open test site, propagation characteristics of unwanted emissions from ITE in a building, the output power of the TV transmitting station, the propagation characteristics of the TV radio waves, and the directivity of the TV receiving antenna. The possibility of disturbances occurring in the Kanto area was predicted and the results show that, in the worst case, a disturbance will appear in about 11% of the areas within 30 m of a building containing such equipment. This also shows that the disturbance can be suppressed by improving the shielding of the equipment or building by as little as 10 dB.
