There is no importance. It is only tradition. In old analogue devices it was easier to use rectified signals and many people was used to do this.

This has one advantage: the signal is simpler, but some information is lost. In most new devices it is possible to choose the signal representation.

The advantage is eventually existing in the case of noisy signals: rectification is normally connected with additional filtering. The noise is lower.
