发明名称 ARRANGEMENT FOR CONVERTING BINARY INPUT SIGNAL INTO CORRESPONDING IN-PHASE AND QUADRATURE PHASE SIGNALS
摘要 In order to effectively reduce a memory size of each of two memories provided in an arrangement for converting a binary input data into the corresponding inphase and quadrature signals, a memory output controller and a sequential logic are provided. The memory output controller includes two polarity control circuits and two input data selectors. The two polarity control circuits are respectively coupled to the two memories, while the two input data selectors are preceded by and coupled to both of the two polarity control circuits. Each of the two polarity control circuits reverses the polarity of the output of the associated memory according to the output of the sequential logic. On the other hand, each of the two input data selectors is arranged to selectively acquire the outputs of the two polarity control circuits depending on the output of the sequential logic.
