摘要： A direct division modulator is provided. The direct division modulator includes a symbol mapper converting the input data from a binary bitstream to a desired frequency deviation, such as where the frequency deviation data encodes the information from the bitstream. A converter generates a divide value using the desired frequency deviation information, and a summer adds an average value to the divide value. A converter quantizes the divide value and shapes quantization noise associated with the quantized divide value. A divider modulates a reference signal with the quantized divide value and generates an output signal.
