Abs

Function: abs (<expr>) Returns the absolute value <expr>. If <expr> is complex, returns the complex modulus of <expr>.

log10(x):=log(x)/log(10);
H(f,r,m):=log10(abs(ev((sin(%pi*f)/sin(%pi*f/r))^m, numer, eval)))*20;
plot2d(H(f,25,3), [f, 0, 1], [y, -100, 100]);
ev(H(0.01,25,3),numer);
ev(H(0.03,25,3),numer);
ev(H(0.04,25,3),numer);
ev(H(0.035,25,3),numer);
ev(H(0.0375,25,3),numer);
ev(H(0.03625,25,3),numer);
ev(H(0.001,25,3),numer);
ev(H(0.003,25,3),numer);
