High dynamic range error rate monitor
Abstract
There is provided an error rate monitor (10) incorporating a counter (30) which is incremented as errors are detected in a data stream passing through an interface unit (20) connected to the counter (30). The counter (30) is also simultaneously decremented at a rate proportional to an exponential of a value presently stored in the counter (30). The monitor (10) thereby provides from the value stored in the counter (30) a measure of error rate in the data stream, the value substantially proportional to a logarithm of error rate in the data stream, thereby providing the monitor (10) with a relatively large error rate monitoring dynamic range.

Error rate monitor with large dynamic range
An error rate monitor (10) is provided which has a counter (30) which is incremented as errors are detected in a data stream passing through an interface unit (20) connected to the counter (30). The counter (30) is simultaneously also decremented at a rate proportional to the exponential of the value currently stored in the counter (30). Thus, from the value stored in the counter (30), the monitor (10) gives a measure of the error rate in the data stream, the value being substantially proportional to the logarithm of the error rate in the data stream so that the monitor (10) receives a relatively large dynamic range for monitoring the error rate. .
