This paper describes the design of a reconfigurabledigital modulator to be integrated in theterrestrial platforms of Brazilian Data CollectingSystem. The modulator proposed is based on theCORDIC algorithm and has several configurableparameters, such as carrier frequency, modulationtype (AM, PM or FM) and modulation index. Themodulator model was coded in VHDL and then prototypedand validated in FPGA. The experimentalresults summarized in this paper shows the modulatorsignals in the output of the system.
