TABLE OF CONTENTS This chapter is an introduction to the Additional Discrete Library. This is the sixteenth library in the Simulink group of libraries and contains the blocks shown below. Their functions are illustrated with examples.
The Transfer Fcn Direct Form II block implements a Direct Form II realization of the transfer function specified by the Numerator coefficients and the Denominator coefficients without the leading [1] coefficient in the Denominator.
The model in Figure 17.1 implements the discrete-time function

In Figure 17.1, the Sample time for the Sine Wave block is specified as 0.1. The num(z) for the Transfer Fcn Direct Form II block is specified as [0.5276 -1.5828 1.5828], and the den(z) is specified as [-1.7600 1.1829]. The leading coefficient 1 in the denominator is excluded. The input and output waveforms are shown in Figure 17.2.
[1] By lead we mean that the leading coefficient 1 in the denominator which has the form 1 + z -1 + z -2
The Transfer Fcn Direct Form II Time Varying block implements a Direct Form II realization of a specified transfer function. Essentially, this block performs the same function as that of the Transfer Fcn Direct Form II block which is described in the previous section, except...
