 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.
