In contrast to linear block codes, not every convolutional code possesses a parity-check  matrix, i.e. not every convolutional code is noncatastrophic. However, the property of being non-catastrophic plays an important role for other characteristics of convolutional codes, such as column distances and free distance as well as self-duality. In this talk, we explain how the catastrophicity/non-catastrophicity of a convolutional code influences its distance properties and its self-duality. We also present some examples for code parameters for  which these characteristics are independent of each other.
