Engineering Contradiction Analysis
1Reliability
If a received signal is stored and an interference signal is generated using the stored signal, then the interference signal can be generated with reference to the original signal characteristics, but processing takes time and an interference signal cannot be immediately generated
Solution Approach 1:
The frequency conversion process is prepared in advance by configuring the converter to perform frequency shifting based on the center frequency of the target frequency band. This allows the system to immediately generate interference signals without needing to store and process the entire received signal, as the conversion mechanism is pre-established
Solution Approach 2:
The invention extracts only the essential characteristic (center frequency) needed for interference signal generation, rather than storing the entire received signal. By identifying and using only the center frequency parameter, the system achieves rapid interference signal generation while maintaining effectiveness
2Speed
If frequency conversion is performed based on center frequency, then immediate interference signal generation is achieved, but multiple conversion stages increase device complexity
Solution Approach 1:
The frequency conversion process is divided into two distinct stages: a first converter that performs initial frequency conversion, and a second converter that performs further frequency conversion. This segmentation allows each converter to be optimized for its specific function, achieving rapid processing while managing complexity through modular design
Solution Approach 2:
The first converter acts as an intermediary between the received signal and the second converter. It performs an intermediate frequency conversion that prepares the signal for the final conversion stage, enabling the system to achieve rapid interference signal generation through a staged approach rather than a single complex conversion
