Abstract

EN UN GRABADOR DE VIDEO, EN EL QUE LA BANDA DE FRECUENCIAS DISPONIBLE HA SIDO AMPLIADA POR MEDIO DE COMPONENTES ELECTRICOS HASTA APROXIMADAMENTE 7,5 MHZ, SE REGISTRA UNA PORTADORA DE TONOS (T1U,T2U) MODULADA POR FRECUENCIA EN LA GAMA ALTA DE FRECUENCIAS (B). EN LA REPRODUCCION SE RECONVIERTE, CON LA PORTADORA MEZCLADORA (M) GANADA DE LA LINEA, DE NUEVO LA FRECUENCIA EN LA FRECUENCIA ORIGINAL (5,5 O 5,74 MHZ). DEBIDO A ELLO LA PORTADORA DE TONOS MODULADA POR FRECUENCIA, SE LIBERA DE ERRORES DE TIEMPO Y DE LA MODULACION ADICIONAL PERTURBADORA.
