Abstract
UN SINTONIZADOR INCLUYE UNA ETAPA DE CONVERSION (O HETERODINANTE) QUE INCLUYE UN OSCILADOR LOCAL Y UN MEZCLADOR, PARA CONVERTIR UNA SEÑAL DE RF QUE SE CORRESPONDE CON UN CANAL SELECCIONADO PARA UNA SEÑAL DE IF. EL OSCILADOR LOCAL TIENE SOLAMENTE UNA PARTE OSCILANTE SINTONIZABLE PARA GENERAR UNA SEÑAL, Y UN CONVERTIDOR DE FRECUENCIAS, TAL COMO UN DIVISOR CONTROLABLE DE FRECUENCIAS, PARA CONVERTIR LA FRECUENCIA DE LAS SEÑALES GENERADAS POR LA PARTE OSCILANTE, DE MANERA QUE EL RECEPTOR SEA CAPAZ DE SINTONIZAR A TRAVES DE LAS BANDAS DE UHF Y DE VHF. EL FUNCIONAMIENTO DEL CONVERTIDOR DE FRECUENCIAS ES SENSIBLE A UN CONTROLADOR DIGITAL, TAL COMO UN MICROPROCESADOR.
