Comparing Toroids...
as their signals travel through the integrator
Its probably useful to have a copy of the integrator circuit in front
of you. These plots are accurate as of 9/5/95.
This is the spice circuit used to generate these
plots.
Input Signal
This signal is meant to simulate a single ping, containing 5 x 1012
protons.
