Popis
Shrnutí:A new closed‐form expression of the spectral coefficients of the digital streams obtained by dyadic digital pulse modulation is presented and validated in this letter. The new expression provides in‐depth insight into the spectral properties of dyadic digital pulse modulation, revealing its applicability as an all‐digital bandpass amplitude modulation technique. Simulations and measurements on a proof‐of‐concept dyadic digital pulse modulation amplitude modulator prototype demonstrate the effectiveness of the approach.
