Roles of the coupling and bypass capacitors in a CE transistor
So, both coupling and blocking capacitors are the same - a charged capacitor acting as a constant voltage source. But in the first case it is connected in series while in the second - in parallel to another voltage source. And both coupling and blocking capacitors do the same - they keep the voltage across themselves constant.

Capacitors and Resistors. ... Applications Where Parasitic Effects Play a Role. Parasitic effects are most prominent at high frequencies. For example, a metal foil 1.0 kΩ resistor with 0.05 pF capacitance at 100 MHz would, in fact, behave as a 0.9995 kΩ resistor, when all parasitic effects are considered. ...
8.2: Capacitance and Capacitors
The fundamental current-voltage relationship of a capacitor is not the same as that of resistors. Capacitors do not so much resist current; it is more productive to think in terms of them reacting to it.
19.5: Capacitors and Dielectrics
A capacitor is a device used to store electric charge. Capacitors have applications ranging from filtering static out of radio reception to energy storage in heart defibrillators. Typically, commercial capacitors have two conducting parts close to one another, but not touching, such as those in Figure (PageIndex{1}).
