Engineering Contradiction Analysis
1Speed
If voltage level is reduced and signal frequency is increased to improve communication performance, then communication speed and efficiency are improved, but probability of malfunction increases
Solution Approach 1:
The receiver detector performs preliminary detection of the reception circuit's active state before actual data transmission begins. By checking whether the reception circuit is in an active state through voltage comparison at the first and second nodes, the system can prevent communication malfunctions before they occur, thereby maintaining high communication speed while improving reliability.
Solution Approach 2:
The system implements a feedback mechanism where the receiver detector continuously monitors the voltage levels at the first and second nodes and provides feedback about the reception circuit's state. This feedback allows the transmission circuit to adjust its operation accordingly, ensuring reliable communication even at high signal frequencies by preventing malfunctions through real-time state verification.
2Measurement precision
If receiver detector uses voltage comparison with reference voltages to detect active state, then detection accuracy is improved, but device complexity increases
Solution Approach 1:
The receiver detector uses parameter changes in voltage levels to detect the active state of the reception circuit. By comparing the voltage at the first node with a first reference voltage and the voltage at the second node with a second reference voltage, the system achieves accurate detection. The use of voltage parameters instead of complex detection mechanisms resolves the contradiction by maintaining high detection accuracy while avoiding excessive circuit complexity.
