==Power saving advantages==

A significant advantage of 8VSB for broadcasters is that it requires much less power to cover an area comparable to that of the earlier [[NTSC]] system, and it is reportedly better at this than the most common alternative system, [[Orthogonal frequency-division multiplexing|COFDM]].{{citation needed|date=March 2021}} Part of the advantage is the lower peak to average power ratio needed compared to COFDM.{{citation needed|date=March 2021}} An 8VSB transmitter needs to have a peak power capability of 6&nbsp;dB (four times) its average power.{{citation needed|date=March 2021}} 8VSB is also more resistant to impulse noise.{{citation needed|date=March 2021}} Some stations can cover the same area while transmitting at an [[effective radiated power]] of approximately 25% of analog broadcast power.{{citation needed|date=March 2021}} While NTSC and most other analog television systems also use a vestigial sideband technique, the unwanted sideband is filtered much more effectively in ATSC 8VSB transmissions. 8VSB uses a [[Low-pass filter|Nyquist filter]] to achieve this. [[Reed–Solomon error correction]] is the primary system used to retain data integrity.

In summer of 2005, the ATSC published standards for Enhanced VSB, or [[E-VSB]] [https://web.archive.org/web/20060214123607/http://www.tvtechnology.com/features/atsc/F_Whitaker.shtml]. Using [[forward error correction]], the E-VSB standard  will allow DTV reception on low power handheld receivers with smaller antennas in much the same way [[DVB-H]] does in Europe, but still using 8VSB transmission.
