Abstract
A cord for suppressing noise from a modem includes a hot wire, a neutral wire, and a signal balancing device. The hot wire is configured to connect to a hot power port of a modem. The neutral wire is configured to connect to a neutral power port of the modem. The signal balancing device is configured to connect to an outer conductor of a coaxial radiofrequency (RF) port of the modem and to the neutral wire or a ground wire. The signal balancing device is configured to balance RF signals transmitted through the coaxial RF port.
Claims20
A system for suppressing noise from a modem, comprising:
- a modem comprising:
- a hot power port;
- a neutral power port;
- and
- a coaxial radiofrequency (RF) port comprising an inner conductor and an outer conductor, the coaxial RF port being configured to communicate signals with an external network;
- and
- a cord comprising:
- a hot wire configured to connect to the hot power port;
- a neutral wire configured to connect to the neutral power port;
- and
- a signal balancing device configured to connect to the outer conductor of the coaxial RF port and to the neutral wire or a ground wire, wherein the signal balancing device comprises:
- a coaxial choke configured to attenuate a predetermined shield current of the signals via field conversion;
- and
- a capacitor connected in series with the coaxial choke, wherein the capacitor is configured to balance the signals transmitted through the inner conductor and the outer conductor of the coaxial RF port.
A cord for suppressing noise from a modem, comprising:
- a hot wire configured to connect to a hot power port of a modem;
- a neutral wire configured to connect to a neutral power port of the modem;
- and
- a signal balancing device configured to connect to an outer conductor of a coaxial radiofrequency (RF) port of the modem and to the neutral wire or a ground wire, wherein the signal balancing device is configured to balance RF signals transmitted through the coaxial RF port.
