Abstract
An expression for the Hamming weight of the (L+1)th order output of a constituent encoder is derived. This expression enables the determination of the inputs that produce outputs of finite weight. It also facilitates the calculation of the (L+1)th order effective free distance (i.e., minimum output weight) dL+1 of the encoder. Expressions and bounds for dL+1 and in particular for d2 and d3 are presented
