Implement time varying Direct Form II realization of transfer function
Simulink / Additional Math & Discrete / Additional Discrete
The Transfer Fcn Direct Form II Time Varying block implements a Direct Form II realization of the specified transfer function. The block supports only single inputsingle output (SISO) transfer functions.
The input signal labeled Den No Lead contains the denominator
coefficients of the transfer function. The full denominator has a leading coefficient of
one, but it is excluded from the input signal. For example, to use a denominator of
[1 1.7 0.72]
, specify a signal with the value [1.7
0.72]
. The input signal labeled Num contains the
numerator coefficients. The data types of the numerator and denominator coefficients can
be different, but the length of the numerator vector and the full denominator vector
must be the same. Pad the numerator vector with zeros, if needed.
The block automatically selects the data types and scalings of the output, the coefficients, and any temporary variables.
