Abstract
Un aparato de desviación incluye un amplificador de desviación acoplado con un circuito de modulación de forma de onda de desviación, tal como un modulador de diodo. Una fuente para generar una señal de modulación. La señal de modulación incluye un componente de corriente alterna periódico simétrico que tiene primera parte del período de rastreo. Un amplificador de retroalimentación altera la amplitud de una primera parte del período de rastreo, para hacer al componente de corriente alterna asimétrico. El componente de corriente alterna asimétrico se acopla con el circuito de modulación de forma de onda de desviación, para la modulación de forma de onda de desviación.
