It could be many things. 1  Gather facts. 2  Rule out equipment... 3  Back to gathering facts... 4  Call Comcast.  Good 1  luck. Have your problems always existed (with your current installation/configuration)?  When speaking with anyone...
A maximum-phase system is the opposite of a minimum phase system. A causal and stable LTI system is a maximum-phase system if its inverse is causal and unstable. That is, 1  The zeros of the discrete-time system are outside the unit circle.
Thermodynamic equilibrium is characterized by the free energy for the whole (closed) system being a minimum. For systems at constant pressure the Gibbs free energy is minimum. The slope of the reaction free energy, Î´Gr with respect to the reaction coordinate, Î¾, is zero when the free energy is at its minimum value.
