Talk:Bit Error Rate Test

Is "10e06" really correct? Ordinarily the number before the exponent should be in the range [0,1], so that 10e06 would be written 1e7.

I've always seen it expressed as x.x e-y. Note the sign; the term Bit Error Ratio demands results < 1 (all errors, statisically improbable).

Another thing: A pseudorandom binary sequence which generates every combination of a 20-bit word, repeats every 1,048,575 bits, and suppresses consecutive zeros to no more than 14.

The example given is oddly specific, and unusual. There are PRBS patterns in several "standard" lengths. In common use are 2^7-1, 2^9-1, 2^15-1, 2^23-1, and 2^31-1. Generally, the one used depends on the channel bit rate. 2^31-1 is almost exclusively used at 10Gb/s or similar.

If there's agreement, I'd suggest removing the text quoted above, replacing with a more general statement or one giving the examples I cited. —Preceding unsigned comment added by 192.32.211.227 (talk) 16:13, 10 September 2009 (UTC)

BERT is also an abbreviation for Bit Error Rate Tester, i.e. the measurement equipment to determine the Bit Error Rate. I couldn't find a Wikipedia article about the Bit Error Rate Tester, but maybe I didn't try hard enough to find it... Michilans (talk) 14:35, 2 November 2009 (UTC)
