One Kind of Pseudo-Rate Modulator Based on Digital Integrated FPGA

One kind of pseudo rate modulator designed with digital integrated FPGA and its application are introduced. Only one integrated digital chip is needed to integrate three channel modulator. This modulator is designed with digital circuit, and is different from that designed with analog circuits or software. The exponent operation of the one order feedback logic is substituted by digital shift. It has the same characteristics of high real time, high precision compared with that implemented by analog circuits, and has the same characteristics of convenience and flexibility compared with that implemented by software. This modulator can overcome the shortcoming of that implemented by analog circuits or software. It is applicable to the satellite control system with incorporated information and integrated electronic technology.
