1Ease of operation
If a switch circuit is configured on the transmission path to control data transmission, then data transmission control capability is improved, but switching noise is generated that interferes with the pre-stage circuit
Solution Approach 1:
An impedance module is introduced as an intermediary component between the output stage circuit and the switch circuit. This impedance module acts as a mediator that blocks the transmission path of switching noise from the switch circuit to the output stage circuit, while still allowing the control function of the switch circuit to operate effectively. The impedance module specifically targets and reduces the harmful noise signals without interfering with the intended data transmission control capability.
2Object-affected harmful factors
If the impedance module is configured between the output stage circuit and the switch circuit, then noise interference is reduced, but the circuit structure becomes more complex
Solution Approach 1:
The impedance module utilizes parameter changes in electrical impedance to achieve noise reduction. By configuring the impedance module with specific impedance characteristics that vary with frequency or signal conditions, the circuit can effectively block noise signals while maintaining simplicity in overall structure. The parameter-based approach allows the impedance module to dynamically differentiate between noise and valid signal without requiring complex circuitry.
