Apparatus for and method of determining twist of clothes being washed in washer
 An apparatus for and a method of determining a twist of clothes being washed in a washer, wherein a sensing signal indicative of the twist of clothes is analyzed, to determine whether the clothes twist signal is a meaningful signal or a noise, so that when the clothes twist signal is the meaningful signal, an operation in a clothes untwisting mode is carried out for minimizing a damage of the clothes. The apparatus includes a clothes twist sensing unit for sensing a torque occurring at a drive shaft due to the distribution of impact applied to an agitator and generating a clothes twist signal according to the sensed torque, a correlation coefficient operating unit for converting the clothes twist signal into a digital signal indicative of a state value of the clothes twist signal, analyzing the state value of the clothes twist signal, and operating a correlation coefficient to be used for determining whether the clothes twist signal is a meaningful signal or a noise, based on the analysis, and a microprocessor for performing a control for executing a clothes untwisting mode, when the clothes twist signal is the meaningful signal, from the correlation coefficient outputted from the correlation coefficient operating unit.
