Abstract : This report summarizes the efforts and results aimed at defining a limit and measurement technique for antenna conducted harmonic and spurious emissions from transmitters with digital modulations. The modulations considered were Frequency Shift Keying, biphase and quadriphase Differential Phase Shift Keying, and Pulse Code Modulation-Frequency Modulation. Derivation of the limit was based on the effect of these modulations on three analog and five digital receiver classes in a typical communication system deployment.
