Substations Coupling Interface Circuits TRIZ Cases
- Data Connection Protection Circuit for Overvoltage Without Bandwidth Loss
A diode-capacitor protection circuit blocks overvoltage and leakage-current damage while preserving data bandwidth and DC signal levels.
- Wideband Filter for DSL Load Coil Audio Notch Compensation
A wideband filter amplifies the 4-8 kHz notch region of DSL load coils, preserving wideband audio while maintaining reliable DSL transmission.
- TAE Plug-In Module for Automated Subscriber-Line Identification
A readable-memory plug-in module identifies subscriber-line connections automatically while its one-time lock prevents removal during maintenance.
