SVC filter is a program designed to expedite the design and analysis of lowpass (and highpass) filters with nearest 5% component values. SVCfilter is 32-bit Windows? electrical filter design software nicely written to help the radio amateur, technician or engineer design and analyze lumped-element lowpass and highpass filters.

SVCfilter features

Cutoff frequency is entered in the usual text box and can be from audio through UHF.Cutoff frequency can be as low as 0.1 Hz, allowing the value of .159155 [ i.e., 1/(2*PI) ] to be used.The graphic output draws the schematic of the filter you have designed, and also plots the responses of that filter (both transmission and reflection). It selects the nearest 5% values for the capacitors and shows those values as well as the exact values and overlays the response plots for the nearest values on top of the original exact-value plot.Tuning buttons allow stepping the cutoff frequency up or down in 1% steps and immediately seeing the new performance of the redesigned filter on the plot.Place the cursor anywhere on the plot and see the transmission, reflection, VSWR and envelope delay values for that frequency.Click on the “Write Elsie File” button to write a file to drive Elsie the filter design and analysis program for followup filter examination in even greater detail.Click on the “Write Spice schematic” button to write a file to drive the LTspice simulator.
