Conclusions
An amplifier containing in its input circuit an overdamped galvanometer possesses for equal fluctuation sensitivity thresholds a smaller reading stabilization time than a tuned amplifier stage either with electron tubes or transistors. This is particularly noticeable in recording extremely small dc emfs and in measuring 10 Hz signals.
