to circuits that contain capacitors and inductors. Unlike the resistor which dissipates energy, ideal capacitors and inductors store energy rather than dissipating it. Capacitor: In both digital and analog electronic circuits a capacitor is a fundamental element. It enables the filtering of signals and it provides a fundamental memory element.
As the frequency decreases, the impedance of the capacitor increases so that the voltage divider of the resistor and capacitor causes the output voltage to decrease, hence the CR circuit works as a highpass filter. Again the same capacitor can be used, the difference is where the output voltage is taken: across the capacitor for a lowpass ...

Filter capacitors. Capacitors are reactive elements, which make them suitable for use in analog electronic filters.

A resistor is just an imperfect conductor, and you can make a resistor just by using a really long wire (as wires themselves have some resistance). Resistors are used in virtually every circuit. A few examples are voltage dividers, filters, and biased active circuits. Capacitors store and release electric charge (kind of like a battery). Their ...
These are simply common mode filter capacitors. In combination to the common-mode choke they filter out common-mode noise (noise present on both lines in respect to ground, or simply (Vline1+Vline2)/2. This is different from Capacitor C1 which filters out differential noise.
To get a simple two port filter you can use combinations of resistors, capacitors and inductors to create various filter types such as high pass and low-pass. Using more than one of each can get you band-pass and notch filter (band reject filter). Using a resistor and a capacitor/inductor you can get 1st order filters.
