(1) In servosystems, the signal whose amplitude and polarity or phase are used to correct the alignment between the controlling and the controlled elements. (2) The name given to the electrical output of a control transformer .
An alloy that changes directly from a solid to a liquid with no plastic or semiliquid state .
An alloy of 63 percent tin and 37 percent lead. Melts at 361o F .
The supply voltage required to activate a circuit .
The current that flows in the primary winding of a transformer when the
secondary is open-circuited; it produces a magnetic flux field. Also called magnetizing current .
A function whose output is a 1 if one and only one of the input variables is a 1 .
A gate that produces a logic 1 output when the inputs are different, but not
when they are the same .
The numeral written in superscript (102) which indicates the power to which the base is to be raised .
