No. The amplified signal bridge (aka phase coupler) is tuned to pick up and amplify the X-10 signal only. It will not prevent noise, but it will not amplify it unless the noise is disguising itself as an X-10 signal :)
As I mentioned in previous posts, in most cases an amplified signal bridge will be needed to acheive reliable X-10 communication in an expansive system. What I mean by an expansive system is where X-10 transmitters and receivers are spread throughout the home. The size of the home is also a factor. As you would expect, the larger the home, the greater the need for this device.
