数字射频存储器 (DRFM )复制信号的相位不连续会使输出信号与输入信号间产生较大的频率误差。 3比特相位量化DRFM对输入信号量化后的每一个相位区间都唯一对应一个 3位二进制码 ,据此导出译码器的结构是一个 3位二进制加法器 ,将译码器输出与延迟取样的信号码比较 ,去控制存储器终止存储。这种相位校正的精度小于π/ 4。
The discontinuous phase of the digital RF memory (DRFM) replica signal causes a large frequency error between the output signal and the input signal. The 3-bit phase-quantized DRFM uniquely corresponds to a 3-bit binary code for each phase interval after quantization of the input signal. The resulting decoder structure is a 3-bit binary adder which outputs the decoder output with a delayed sample Number comparison, to control the memory to terminate storage. The accuracy of this phase correction is less than π / 4.
