  • Signal relay circuit for securing amplitude of voltage of transmitting signals
    Patent number: 7362796
    Abstract: In a signal relay circuit according to the present invention, while a capacitor serves to pass an AC component of a digital signal having a first potential level and a second potential level higher than the first potential level, a first resistor and a second resistor serve to secure an amplitude of voltage of the digital signal between the first potential level and the second potential level as received from the capacitor.
