Abstract
The present technique relates to a cable apparatus, a noise canceling apparatus, and a noise canceling method that allow reliable removal of noise induced by a radio wave. A cable apparatus is provided with wiring for input which is electrically connected to a device and through which an input signal and an RF noise signal induced are transmitted, and wiring for noise detection which is electrically connected to an adjustment element enabled to be adjusted to an impedance corresponding to an input impedance of an output circuit of the device and in which the RF noise signal is induced. Thus, noise included in a signal from the first wiring can be reliably removed. The present technique can be applied to a noise canceling system, for example.
Claims33
A cable apparatus comprising:
- wiring for input which is electrically connected to a device and through which an input signal and an RF noise signal induced are transmitted, and
- wiring for noise detection which is electrically connected to an adjustment element enabled to be adjusted to an impedance corresponding to an input impedance of an output circuit of the device and in which the RF noise signal is induced.
A noise canceling apparatus comprising:
- a signal processing section configured to remove an RF noise signal to an input signal transmitted through wiring for input electrically connected to a device, using an RF noise signal induced in wiring for noise detection electrically connected to an adjustment element enabled to be adjusted to an impedance corresponding to an input impedance of an output circuit of the device.
A noise canceling method comprising:
- by a noise canceling apparatus,
- removing an RF noise signal to an input signal transmitted through wiring for input electrically connected to a device, using an RF noise signal induced in wiring for noise detection electrically connected to an adjustment element enabled to be adjusted to an impedance corresponding to an input impedance of an output circuit of the device.
