A note on the correlation function of nonindependent, overlapping pulse trains

Biorci and Mazzetti
^{1}
have found a general formula for the correlation function of nonindependent, overlapping pulse trains; however, its application involves considerable mathematical difficulties in general.
^{2}
This paper shows how these difficulties can be avoided and it provides, in addition, a necessary and sufficient condition whereby the nonindependent result is identical with the independent pulse result.
