Control System Parts 6

This part is characterized by the following attributes:
ROW1 = 0Hz 0 0
ROW2 = 5kHz 0 -5760
ROW3 = 6kHz -60 -6912
DELAY =
R_I =
MAGUNITS =
PHASEUNITS =
Since R_I, MAGUNITS, and PHASEUNITS are undefined,
each table entry is interpreted as containing frequency,
magnitude value in dB, and phase values in degrees. Delay
defaults to 0.
This produces a PSpice A/D netlist declaration like this:
ELOFILT 5 0 FREQ {V(10)} = (0,0,0) (5kHz,0,-5760)
+ (6kHz,-60,-6912)
Since constant group delay is calculated from the values for a
given table entry as:
group delay = phase / 360 / frequency
An equivalent FTABLE instance could be defined using the
DELAY attribute. For this example, the group delay is 3.2 msec
(6912 / 360 / 6k = 5760 / 360 / 6k = 3.2m). Equivalent attribute
assignments are:
ROW1 = 0Hz 0 0
ROW2 = 5kHz 0 0
ROW3 = 6kHz -60 0
DELAY = 3.2ms
R_I =
MAGUNITS =
PHASEUNITS =
This produces a PSpice A/D netlist declaration like this:
ELOFILT 5 0 FREQ {V(10)} = (0,0,0) (5kHz,0,0) (6kHz,-60,0)
+ DELAY=3.2ms
