El oscilador de doble T que se muestra en la Figura 1 puede generar señales sinusoidales de hasta unas pocas decenas de kilohertz. Tenga en cuenta que los componentes de doble T deben mantener una relación de valores  El potenciómetro ajusta el punto de oscilación puede ser sustituido por una resistencia fija del mismo valor. El circuito trabaja con tensiones de alimentación de 9 a 15 V y transistores equivalentes como el BC548 puede ser utilizado.

 

Figura 1 - Oscilador doble T.

    En la simulación disponible esperar un poco hasta que comiencen las oscilaciones, que puede durar varios ciclos. Las formas de onda disponibles en este circuito, sons mostradas el osciloscopio virtual del Multisim Blue en la figura 2.
