In cascade connection, it can be a AC coupling capacitor at both end to isolate the circuit. Isolating DC from input side or DC single to load side if they are at different reference supplies. If pull down to ground, it can be a protective capacitor for overshoot when capacitance is big enough, or can be used for shorting high frequency to ground to restrain pulse jamming when capacitance is small. It's value depends on the application, and it's influence to the circuit like slew rate and some chip's maximum capacitance load should be considered.
Including a series capacitor in the input and/or output circuit of the transistor. If the capacitor in the output circuit is omitted there will be a dc component in the output.
In an integrator circuit, the resistor (R) and capacitor (C) work together to produce an output that represents the integral of the input signal over time. The capacitor stores charge, causing the output voltage to change based on the input voltage applied through the resistor. As a result, the output voltage increases or decreases depending on the input signal's magnitude and duration, effectively creating a smooth, continuous output that reflects the cumulative input over time. The time constant of the integrator is determined by the product of R and C, influencing how quickly the output responds to changes in the input.
ANSWER In rectifiers for power supplies, the capacitor size is determined by the allowable ripple on the output. This can be determined by the rate at which the capacitor is drained. Specifically, this rate is the current drawn from the capacitor. Assume a half wave rectifier made from four diodes. For part of the cycle, the output current is supplied by the rectifier diode. This is also when the capacitor is charged. While the rectifier is not supplying current -- when the input waveform has dropped below the output voltage -- the capacitor must supply the current. Then, as the input waveform rises above the capacitor voltage, the rectifier supplies the current to charge the capacitor and the output circuit.

Ripple voltage in a capacitor-input filter primarily arises from the charging and discharging cycles of the capacitor. When the rectifier conducts, the capacitor charges to the peak voltage of the input signal. As the load draws current, the capacitor discharges, causing the voltage to drop until the rectifier conducts again, resulting in a voltage ripple. The magnitude of this ripple depends on factors such as the load current, capacitance value, and input frequency.

They could be either or both, depending on their purpose.
A capacitor is primarily considered an input process component in electrical systems, as it stores and releases electrical energy in response to voltage changes. It can influence how signals are processed within a circuit, acting as a filter or smoothing component. However, it also plays a role in output processes when it discharges energy to power other components or systems. Therefore, its function can span both input and output depending on the context of its application.
It's an output device. Its sole purpose is to let you hear what sounds the computer is playing.
To design a simple integrator with an op amp, place a resistor and capacitor in series in the feedback loop, between output and inverting input. Place another resistor from circuit input to the inverting input. Ground the non-inverting input. The current through the input resistor will be balanced with the current through the feedback resistor. Since there is a capacitor also, the voltage slope at the output will be proportional to the current. If you want the capacitor to discharge faster in one direction, you can place a diode (and optional resistor) across the feedback resistor. This works because the capacitor resists a change in voltage, proportional to current, and inversely proportional to capacitance. The equation is dv/dt = i/c. This means that dv/dt is linear with constant i and c. In this configuration, a constant current input will be balanced with a linear voltage ramp on the output, limited only by the range of the op amp. Constrast this with a simple RC circuit - with constant voltage, the RC circuit will exhibit a logarithmic output. If, for instance, you were to drive this circuit with a square wave, the output would be triangular. With the diode, the output would be sawtooth.
The purpose is to buffer the input for monitoring purposes
