ABSTRACT:
An inversion pulse for wideband application is obtained from a simple nonlinear amplitude modulation wherein the amplitude is modulated in accord with A(t)=A.sub.0 {1-.vertline. sin .beta.t.vertline..sup.n } and the entire pulse is frequency modulated such that the phase varies as .phi.(t)=.phi..sub.0 +1/2 kt.sup.2.
