POSITIONAL WEIGHTINGThe value given a digit based on the digit's position within a given number [13]. | |
POSITIVE ALTERNATIONThe part of a sine wave that is above the reference line [2] [10] [12]. | |
POSITIVE CLAMPERA circuit that clamps the lower extremity of the output waveshape to a dc potential of 0 volts [9]. | |
POSITIVE FEEDBACKFeedback in which the feedback signal is in phase with the input signal. Also called REGENERATIVE FEEDBACK [8]. | |
POSITIVE LOGICThe form of logic in which the more positive logic level represents 1 and the more negative level represents 0 [13]. | |
POSITIVE TEMPERATURE COEFFICIENTThe characteristic of a conductor in which the resistance increases as temperature increases [7]. | |
POTENTIAL ENERGYEnergy caused by the position of one body with respect to another body or to the relative parts of the same body [1]. | |
POTENTIOMETERA variable resistor, used as a position sensor in servosystems, having a terminal connected to each end of a resistive element and a third terminal connected to a wiper contact. The output is a voltage that is variable depending upon the position of the wiper contact. The potentiometer is commonly referred to as a variable voltage divider. It, in effect, converts mechanical information into an electrical signal [1] [15]. | |
POWERThe rate of doing work or the rate of expending energy. The unit of electrical power is the watt [1]. | |
POWER AMPLIFIERAn amplifier in which the output-signal power is greater than the input-signal power [8]. | |
