- resonance frequency for acceleration response (
)
- for completeness, listing the resonance frequency for the three quantities in question
- notice
by comparing with the resonance frequency for displacement as discussed last time
Mean power:
-
is true when
and
have the same time dependence (e.g., both propagating forward/backward in time) in their complex power representation
-
, where
Power resonance and bandwidth
- Consider the half power points, whose difference gives the bandwidth
- this provides a second definition of the quality factor
Canonical form of the LCR circuit equation
Impedance: Force divided by the velocity
- encapsulating both magnitude and phase shift information
