Abstract

"RESSONADOR MUNIDO DE UM DISPOSITIVO RESSONANTE E COM UM CIRCUITO DE SELEçãO PARA SELECIONAR UM MODO DE RESSONâNCIA". Ressonador munido de um dispositivo ressonante e de um circuito de seleção para selecionar um modo de ressonância. O circuito de seleção é formado por um oscilador de primeira ordem que é munido de uma entrada de sincronização e cuja saída é conectada com a entrada de excitação do dispositivo ressonante, a saída do dispositivo ressonante sendo conectada com a entrada de sincronização do oscilador de primeira ordem para sincronizar o oscilador e o sinal de saída do ressonador sendo derivado do dispositivo ressonante ou oscilador.
