TimeSpaceLightForce Posted November 19, 2014 Report Share Posted November 19, 2014 A 4-way binary chip has 1 error bit. Which bit is it? Switch it in order to set the sum of all totals to zero. Quote Link to comment Share on other sites More sharing options...
0 DejMar Posted November 20, 2014 Report Share Posted November 20, 2014 Without any given specifications of what a 4-way binary chip is, I can only envision the question to be asking for a result of symmetry. If this is the case, the error bit is in the second column of the fourth row. Quote Link to comment Share on other sites More sharing options...

If this is the case, the error bit is in the second column of the fourth row. For puzzle purposes its an 4x4 array of on/off LEDs,with glow wires that indicate negative values. It totals rows of binary numbers in 4 orientations.If the error bit is toggled..the value of A+ A + -A + -A=0 ( lits to A A -A -A ). Quote Link to comment Share on other sites More sharing options...
0 DejMar Posted November 21, 2014 Report Share Posted November 21, 2014 | | 1101- The error bit is located in the first row, second column. 0011 [(-13+3-12+13)+(-13+4+11-11)+(13-13-2+11)+(-11-3+12+11)] = 0 -1100- -1101 || 1 Quote Link to comment Share on other sites More sharing options...
