Abstract : It was conjectured that the phase shift across the principal locking-in region (p = q = 1) was Pi. This study is an attempt to verify the conjecture and generalize the result somewhat. The results include the case of a second-order scalar system, where the unforced system is an equation of the van der Pol type with an orbitally stable limit cycle. (Author)
