Abstract
A modulation circuit uses pre-calculated and stored data to generate the modulated output. The modulator architecture uses pre-calculated, Gaussian filtered sine and cosine responses that are stored in a ROM (read-only memory) or other memory structure. The modulator output is then calculated as a simple sum of values read from the ROM and controlled by the input burst data stream.
