English: This was created using the following gnuplot source:
 This plot was created with Gnuplot.

See my page for details. - Omegatron 01:37, Mar 5, 2005 (UTC) Replacement for :Image:DBA.gif Created with maxima (or gnuplot, I guess) and edited in the GIMP, since I don't have the patience to scour documentation for things I am only going to use once or twice. H:(kA*s^4)/((s+129.4)^2*(s+676.7)*(s+4636)*(s+76655)^2); H:ev(H,s=%I*w); H:ev(H,kA=7.397057228624816E+9); H:ev(H,w=2*%PI*f); SET_PLOT_OPTION([GNUPLOT_PREAMBLE, "set log x"]); plot2d(20*log10(abs(H)),[f,10.1,20000]); No, I don't know what I'm doing. with my custom functions (in maxima-init.mac): convert voltage gain to decibels: db(x):=float(20*log(x)/log(10)); convert decibels to voltage gain: idb(x):=float(10^(x/20)); electrical elements in parallel: INFIX("||")$ "||"(x,y):=x*y/(x+y); |
