Negative Feedback Seismometers

Benefiting from negative feedback

This article discusses why it is so hard for people to benefit from negative feedback. We examine factors involved in the effective use of negative feedback. Our analysis suggests that the main obstacles to the effective use of negative feedback stem from the failure to obtain it and the failure to conduct an accurate appraisal of it. This is in contrast to research indicating that the main obs...

Negative Feedback Revisited

Rules are derived for choosing one among the four kinds of basic amplifiers to be embedded in a particular passive feedback network. The loop transmission is identified and conditions for mismatch are obtained from a unified analysis of feedback circuits. Past experience gained with voltage mode basic amplifiers, the laws of duality and mismatch are applied to choose the building blocks employe...

Calibration of Seismometers Using Ground Noise

We have developed and tested a new technique for calibration of seismometers using continuous recordings of ground noise. The method is founded on analytic techniques recently developed for estimation of transfer functions in magnetotellurics. We find that the technique can produce precise, absolute calibration measurements on sensors that do not have calibration coils. The data used are obtain...

IX - Negative Response Relevance Feedback

When friends exchange negative feedback

In four studies, we document an increase in the amount of negative feedback friends and colleagues exchange as their relationship deepens. We find that both actual and perceived relationship depth increase the amount of negative feedback people seek from and provide to each other, aswell as their tendency to invest in a focal (relationship or performance) goal in response to negative feedback. ...
