Abstract
A transmission line includes a signal terminal for inputting a first signal and a second signal, a first wire coupled to the signal terminal for transmitting the first signal, a second wire coupled to the signal terminal for transmitting the second signal, a filtering module coupled to the first and second wires for receiving the first and second signals to filter out noises of the first and second signal, a third wire coupled to the filtering module for transmitting the first signal, and a fourth wire coupled to the filtering module for transmitting the second signal.
Claims4
A transmission line, comprising:
- a signal terminal for inputting a first differential signal and a second differential signal;
- a first wire coupled to the signal terminal for transmitting the first differential signal;
- a second wire coupled to the signal terminal for transmitting the second differential signal;
- a filtering module coupled to the first and second wires for receiving the first and second signals to filter out noises of the first and second differential signals;
- a third wire coupled to the filtering module for transmitting the first differential signal;
- and
- a fourth wire coupled to the filtering module for transmitting the second differential signal;
- wherein the filtering module comprises:
- a first differential choke coupled between the first and third wires for filtering out a differential mode noise of the first differential signal;
- and
- a second differential choke coupled between the second and fourth wires for filtering out a differential mode noise of the second differential signal;
- wherein, the first and second differential chokes are dual in-line package (DIP) differential chokes.
A filtering module, utilized in a transmission line, used for filtering out noises of first and second differential signals transmitted by the transmission line, and comprising:
- a first differential choke coupled between first and third wires of the transmission line for filtering out a differential mode noise of the first differential signal;
- and
- a second differential choke coupled between second and fourth wires of the transmission line for filtering out a differential mode noise of the second differential signal;
- wherein, the first and second differential chokes are dual in-line package (DIP) differential chokes.
