✦ Synopsis

a way that a*:::;: 0 if non-sensitivity is absent. The latter requirement makes that in some important cases the condition (1) is not satisfied.

An attempt was made [3A] to prove Popov's frequency criterion for pulse-width systems, which is weaker than the criterion (I). However it was unsuccessful as the proof in was based on a false statement:
