单词 RectificationOfAntiperiodicFunction
释义

rectification of antiperiodic function


Let the positive number p be the antiperiod of the real function f and

f(t)0for  0<t<p.

Then the functionMathworldPlanetmath f1 defined by

f1(t):=max{f(t), 0}={f(t)forf(t)>0,0   forf(t)0

is the half-wave rectification of f and the function f2 defined by

f2(t):=|f(t)|

is the full-wave rectification of f.  They are periodic (http://planetmath.org/PeriodicFunctions), the former with period (http://planetmath.org/PeriodicFunctions) 2p and the latter with p.

The Laplace transformsDlmfMathworldPlanetmath are

{f1(t)}=11-e-psF(s),
{f2(t)}=1+e-ps1-e-psF(s).
