... and scaling parameters from the inputs of each atomic operation to its outputs. Table 11.2 summarizes the word-length and scaling propagation rules for the different atomic operations. The superscript ... we have managed to transform a non-linear time-invariant system into a linear time-varying system. This linearity allows us to predict the error at the output of the system due to...
