Abstract
SE PRESENTA UN NUEVO PROCEDIMIENTO DIGITRAL QUE POSIBILITA LA DETECCION DE FRECUENCIA INSTANTANEA DE SEÑAL DE ALTA FRECUENCIA CON PULSACIONES EN LAS ZONAS DE PICOSEGUNDO. ADEMAS ES APROPIADO PARA LA INTEGRACION MONOLITICA SOBRE UNO O VARIOS CHIPS-SEMICONDUCTORES. EL NITIDO PROCEDIMIENTO PARALELO SE BASA EN EL PRINCIPIO DE INTERFENOMETRO MENCIONADO Y PUEDE EFECTUAR DIRECTAMENTE LA DIRECCION DE LAS SEÑALES DE ENTRADA EN LA ZONA DE FRECUENCIA ORIGINAL. PARA LA REALIZACION DE ALTERNAR ELEMENTOS DE DEMORA, COMPARADORES Y CONEXIONES ALTERNATIVAS SENCILLAS (EX-OR/NOR-ALTERNADOR).COMO DISTRIBUIDOR DE SEÑALES Y CURSOR DE FASES SE UTILIZA UNA DISPOSICION DE ACOPLAMIENTO HIBRIDO (3DB).
