*** OPTIONS ***
Input K or Kpz ?
────────────────
If you choose K, the transfer function with poles and zeros is:
s s
(1 - ──)(1 - ──)....
z1 z2
G(s) = K ────────────────────
s s
(1 - ──)(1 - ──)....
p1 p2
If your choice is Kpz, then the transfer function with poles and
zeros is:
(s - z1)(s - z2)....
G(s) = Kpz ────────────────────
(s - p1)(s - p2)....
z1, z2, ... are the zeros and p1, p2, ... are the poles.
These expressions are maintained in all calculation processes until
the option is changed again.
│ Warning:
│ In analog systems the choice of K or Kzp influences the static
│ gain of feedback systems if poles or zeros are relocated from the
│ forward path of the control loop to the feedback path of the
│ control loop. Therefore it is recommended to choose K in feedback
│ situations.
Coord Cart or pol?
──────────────────
Poles and zeros are entered and shown in either Cartesian coordi-
nates (real and imaginary parts) or in polar coordinates (modulus
and argument).
PlotTitles ?
────────────
If you choose 'PlotTitles', tables and plots are shown without a
menu bar with program instructions. Those tables or plots may be
equipped with a title of your own choice.
This feature was introduced for tables and plots in publications.
Grids in plots ?
────────────────
The time response plots and the frequency analysis plots may be
equipped with a grid. The root-loci plots never have a grid.
Print-size ?
────────────
If you choose A5, plots are printed in the portrait position. The
print takes about half an A4 page. If you choose A4, plots are
printed in landscape position. The print fills the whole A4 format.
