Z Transform 4 Poles Impulse, Step and Ramp Response.
The Z transform of a 4 pole (2 complex conjugate pairs) system is
The variation of the impulse(cyan) response with the pole location
is illustrated by the following applet with Fn = 0.
The unit circle is shown in magenta, the real Z axis
is in black, the imaginary Z axis is in pink and the pole
location is shown as a green "x".
Changing n shows the effect of changing the number of zeros of the
Fn = 1 shows the step response.
Fn = 2 shows the ramp response.
Fn = 3 shows numerical values of the impulse response.
Fn = 4 shows numerical values of the the step response.
Fn = 5 shows numerical values of the the ramp response.
