Abstract
Multilevel modulators based on carrier shifting reach their minimum harmonic content only through asymmetrical sampling and proper phase shifting. As far as their implementation challenges microcontrollers and DSP's peripherals, the use of field programmable gale arrays (FPGA) becomes attractive. In fact, they allow the design of "ad-hoc" digital modulators with the desired number of timers using hardware description languages. This paper addresses the problem developing a modulator using a FPGA. After a theoretical discussion of the problem, the development using an Actel ProAsicPlus FPGA starter kit is described and analysed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
