专利汇可以提供Multiplying device专利检索,专利查询,专利分析的服务。并且PURPOSE:To complete one multiplication of complex numbers within the reference time of a memory by regarding a maltiplic and expressed by a binary number as an address in an ROM and writing the real and imaginary number parts of the multiplied result to the corresponding content of the ROM. CONSTITUTION:A register 1 stores An-k information encoded into a binary number so as to assign a number to the information. An analog/digital (A/D) converter 2 converts the real number part of an error Yn-An outputted from a receiver into digital information. In the same manner an A/D converter 3 converts the imaginary number part of the Yn-An into digital information. Outputs of 9 bits in total from the register 1, the A/D converter 2 and the A/D converter 3 are inputted to the address of an ROM4. The ROM4 has 2N outputs and the N outputs and the remaining N outputs correspond to the real number and imaginary number of a multiplied result respectively and are displayed as binary numbers. By said procedure, A/D conversion of about 3 bits can be maintained at the accuracy of abuut 6 bits for a signal level.,下面是Multiplying device专利的具体信息内容。
