There are various ways to derive multilevel converter topologies as pointed out by the author's previous work. This letter proposes a voltage-source generalized topology that unifies several and also incorporates bidirectional switches. Most of known can be derived from this new it. Examples have been given in letter. helps understand complicated topologies, especially those with switches it us...

The accurate estimation of the separation between two signals is at core many modern technologies. We show new quantum-inspired schemes able to estimate that quantum limit. method works in spatial, temporal, and frequency domains. question whether optical coherence brings any metrological advantage mode projections discussed.
