Abstract
TRANSDUCTOR DE FRECUENCIA DE ONDA SOSTENIDA Y BUCLE CON SINCRONIZACION DE FASE. EL CIRCUITO QUE PROPORCIONA SEÑALES DE ENTRADA DE CORRIENTE ALTERNA CONSISTE EN: UN DISPOSITIVO MULTIPLICADOR (14) PARA RECIBIR LA SEÑAL DE ENTRADA (10) Y UNA SEÑAL DE REALIMENTACION (16) PARA PROPORCIONAR UNA SEÑAL DE ERROR (20) PROPORCIONAL AL PRODUCTO DE LAS SEÑALES DE ENTRADA Y DE REALIMENTACION; UN DISPOSITIVO INTEGRADOR (22) QUE RESPONDE A LA SEÑAL DE ERROR PROPORCIONANDO UNA PRIMERA SEÑAL DE SALIDA QUE TIENE UN VALOR PROPORCIONAL A LA FRECUENCIA DE LA SEÑAL DE ENTRADA DE CORRIENTE ALTERNA; Y UN DISPOSITIVO DE REALIMENTACION (34, 36, 18) QUE INCLUYE UN DISPOSITIVO OSCILADOR (18) PARA PROPORCIONAR, EN RESPUESTA A LA PRIMERA SEÑAL DE SALIDA Y EN FUNCION DE LA MISMA, UNA SEÑAL DE SALIDA SINCRONIZADA EN FASE QUE TIENE UNA FRECUENCIA PROPORCIONAL A LA DE LA SEÑAL DE ENTRADA.
