In electronic logic circuits, a pull-up resistor (PU) or pull-down resistor (PD) is a resistor used to ensure a known state for a signal. [1] It is typically used in combination with components such as switches and transistors , which physically interrupt the connection of subsequent components to ground or to V CC .

−20%, or for components with uncritical values such as pull-up resistors. The calculated constant tangential tolerance for this series gives (3 √ 10 − 1) ÷ (3 √ 10 + 1) = 36.60%, approximately. While the standard only specifies a tolerance greater than 20%, other sources indicate 40% or 50%.

There is nothing special about pull-up or pull-down resistors, it's just how the resistors are connected in a circuit. The voltage drop across any resistor depends on the current flowing; in a circuit, currents can change and consequently the voltages at specific points in that circuit may go up at one end of what is called a pull-up resistor ...
Variable resistors can be used to adjust circuit elements (such as a volume control or a lamp dimmer), or as sensing devices for heat, light, humidity, force, or chemical activity. Resistors are common elements of electrical networks and electronic circuits and are ubiquitous in electronic equipment. Practical resistors as discrete components ...
Articulation is a musical parameter that determines how a single note or other discrete event is sounded. Articulations primarily structure an event's start and end, determining the length of its sound and the shape of its attack and decay.
