- * \brief Detect the peak of a signal

- *
- * If a peak is detected, this block outputs a 1,
- * or it outputs 0's.
- *
- * \param threshold_factor_rise The threshold factor determins when a peak
- * has started. An average of the signal is calculated and when the
- * value of the signal goes over threshold_factor_rise*average, we
- * start looking for a peak.
- * \param threshold_factor_fall The threshold factor determins when a peak
- * has ended. An average of the signal is calculated and when the
- * value of the signal goes bellow threshold_factor_fall*average, we
- * stop looking for a peak.
- * \param look_ahead The look-ahead value is used when the threshold is
- * found to look if there another peak within this step range.
- * If there is a larger value, we set that as the peak and look ahead
- * again. This is continued until the highest point is found with
- * This look-ahead range.
- * \param alpha The gain value of a moving average filter
