On the passivity criterion for LTI N-Ports
Circuit theory the standard linear distributed higher mathematics the theory of distribution
2015/8/13
Existing proofs of the passivity criterion for linear, time-invariant, distributed N-ports are either incorrect or too involved, requiring the use of advanced mathematics such as distribution theory. ...
Multi-degree ROADM based on massive port count WSS with integrated Colorless ports
