 	The ratio between output and input sampling rate is the \index{interpolation factor} \textbf{interpolation factor} $M$.
 	\begin{equation}
-		M = \frac{T_{S,o}}{T_{S,i}} = \frac{\omega_{S,o}}{\omega_{S,i}} = \frac{T_{S,i}}{T_{S,o}} \qquad, M \in \mathbb{N}

 	The decimation factor $M$ must be a positive integer.
