Abstract
APARATO DE PROCESADO DE SEÑAL PARA LA SINTETIZACION DE UNA SEÑAL TEMPORAL. EL APARATO DE PROCESADO DE SEÑALES QUE SE DESCRIBE EMPLEA UNA ARQUITECTURA DE LINEA PARA ANALIZAR EN TIEMPO REAL RETARDADO EL ESPEECTRO DE FRECUENCIAS DE UNA COMPONENTE DE INFORMACION (CON UNA O MAS DIMENSIONES) DE UNA SEÑAL TEMPORAL DADA CON UN VALOR MAXIMO DE LAS FRECUENCIAS DE INTERES DADO (F0) Y, POSTERIORMENTE, SINTETIZAR LA SEÑAL EN UN TIEMPO REAL RETARDADO, A PARTIR DE SU ESPECTRO DE FRECUENCIA ANALIZADO. DE APLICACION ADECUADA PARA EL PROCESAMIENTO DE IMAGENES EN TIEMPO REAL RETARDADO DE LAS FRECUENCIAS ESPACIALES BIDIMENSIONALES DE IMAGENES DE TELEVISION DEFINIDAS POR UNA SEÑAL DE VIDEO TEMPORAL.
