text: what is impulse noise protection? this is in the context of dsl systems. impulse noise is generated by very common things at home such as turning on/off the microwave, iron, television, radio, etc. it is a burst noise that affects multiple carriers in a dmt system.  impulse noise protection refers to protecting against impulse noise by using reed solomon encoding and scrambling so that information bits from one carrier are well distributed into several frames and even a broad burst can only impact a few bits that can be corrected using reed solomon error correction.
