Digital modulation with arbitrary input sampling and output modulation frequencies |
摘要 |
An arbitrary modulation frequency of a modulating signal is selected. The modulating signal is applied to an information-bearing signal, where such modulation is carried out through digital signal processing operations. The digitally modulated signal is resolution-reduced and the quantization noise introduced by such is shaped to locate a spectral null in the noise transfer function of the resolution reducing modulator at the modulation frequency. Thus, the modulation frequency can be selected independently of the clock frequency at which the resolution-reduced samples are converted to an analog signal. |
