Measuring Your Process Capability
Planning, Design & Analysis
Process capability is the long-term performance level of the process after it has been brought
under statistical control. It is the ability of the combination of your 5 M's to produce a product
Properties of Lossless Ladder
- The circuit is made up of inductors and capacitors, and so can be described as lossless
or as reactance.
o The arrangement is. such that all series elements are inductors and all shunt elements
are capacitors.
- At zero
SENSITIVITY ANALYSIS
Sensitivity definition criterion to compare circuit configurations
and to establish practical usefulness
In practice real circuit components deviate from
their nominal values due to:
environment (temperature, humidity etc)
