We show how the shapes of the observed phase-averaged spectra as well as energy-integrated pulse profiles depend on the orientation for classical and millisecond pulsars.4 pages, 5 Postscript figures, use moriond.sty, latex2e and dvips2e, to apear in the proceedings of the 22nd Moriond Astrophysics Meeting, Les Arcs 2002Astrophysicstext
