Elsie is an uncommon commercial-grade lumped-element ("L-C") electrical filter design and network analysis program, directed toward the engineer or technician involved in that line of work.
This filter design program designs and then analyzes filters with a wide variety of topologies and families and with specified orders, bandwidths, impedances and the like. The usual filter familes of Butterworth, Chebycheff, Cauer (including the zig-zag transform), Bessel, Gaussian, Constant-K and M-derived are covered.
It shows how to use Murata EMI Filters and Chip Capacitors in a circuit.
Spectrum CASCADE allows the engineers to select the RF/Microwave components.
