RECEIVER FOR DIGITAL BROADCASTING |
摘要 |
PROBLEM TO BE SOLVED: To realize miniaturization by reducing a circuit scale. SOLUTION: At the time of quadrature detecting of a received digital modulation signal, the received digital modulation signal is not frequency-converted but detected in quadrature mode with the received frequencies. Thus, it is not necessary to provide any frequency converting circuit which is necessary in a conventional manner. |
