A method for producing feebly damped high-frequency electrical oscillations for laboratory measurements
L.W. Austin · Bulletin of the Bureau of Standards · 1908
The problem of producing high frequency oscillations of suffi- cient constancy for accurate laboratory experiments has always been a difficult one.Even with large induction coils and high- potential transformers the fluctuation in intensity amounts frequently to from ten to twenty per cent.The problem becomes especially difficult in the experimental testing of sensitive receivers, as in these experiments the use of any except the smallest induction coils is impossible unless they are separated from the receiving apparatus by a very great distance.Besides lack of constancy, v.c.
