-In comparison to water , capacitor is like a dam in the middle of our water flow, storing water for some time.+In comparison to water , capacitor is like a dam in the middle of our water flow, storing water for some time. In both cases, if no current/water flows into or out of the capacitor/dam, the water level/voltage remains constant. And the more current/water flows in or out, the faster the water level/voltage changes.

 The signal also has to be quantized in voltage/amplitude, because the computer has to represent each sample as a single number (with limited precision, often an integer (float for high precision) ). The signal also has to be quantized in voltage/amplitude, because the computer has to represent each sample as a single number (with limited precision, often an integer (float for high precision) ).

 In the **digital case**, the circuit around the transistor is designed so the input signal (current for a BJT or voltage for a FET) is large enough to turn on the transistor much more than the actual needed output current, or small enough to turn off the transistor completely.  In the **digital case**, the circuit around the transistor is designed so the input signal (current for a BJT or voltage for a FET) is large enough to turn on the transistor much more than the actual needed output current, or small enough to turn off the transistor completely.
