Circuit fragments:
	Oscillators – timing circuit, predetermined frequency output based on an input
	Differentiators – circuit dependent on input change
	Integrators – circuit dependent on input average
	Filters – circuit that favors one frequency over another
Capacitor make up of two conductors separated by an insulator --|::|-- an example is two conductive metal plates separated by a piece of ceramic used as an insulator.
Two equations associated with capacitor behavior:
	Static description	Q = C / V
	Q = charge
	C = capacitance
	V = voltage  
	Dynamic description	I = C * dV / dt  
Time derivative of static description, higher current flow equals faster voltage change
