O termo “varredura” no contexto mencionado refere-se à deflexão<\/a> horizontal do feixe de elétrons em um CRT (tubo de raios catódicos<\/a>)<\/strong>. Essa deflexão<\/a> é um dos dois movimentos principais do feixe dentro do CRT, sendo a outra a deflexão<\/a> vertical.<\/p>\n\n\n\n

No CRT, a deflexão<\/a> horizontal permite que o feixe de elétrons percorra a tela de forma controlada no eixo horizontal. Isso é realizado por bobinas ou placas de deflexão<\/a> que produzem um campo<\/a> elétrico ou magnético, deslocando o feixe de elétrons lateralmente. Esse movimento é sincronizado com a entrada do sinal<\/a> de vídeo<\/a>, garantindo que a imagem seja desenhada linha por linha, de forma sequencial, em uma representação visual.<\/p>\n\n\n\n

Essa técnica de varredura horizontal é fundamental em sistemas de exibição, como os osciloscópios e televisores analógicos, sendo parte crucial do processo de formação de imagens ou gráficos em tempo real.<\/p>\n","protected":false},"excerpt":{"rendered":"
