WebMay 14, 2013 · 1. Found the solution to my problem, the ^ is a bitflip. Thus if you have a bitmask and use the xor operator on the mask, you flip the bit on that place. E.g. 1010 ^ (1<<1) results in 1000. Same goes for 1000 ^ (1<<1) = 1010. The substraction also works, but with the xor operator you know for certain that you only touch the bit at that place ... WebHowever, the effects of such dynamic modulus should be minor compared to the effect from (0)-(1) bit programming. For example, with the (⋅⋅⋅0⋅⋅⋅) sequence, a 10% change in E would only shift the predicted bandgap frequency by around 35 Hz, much less than the bandgap frequency changes shown in Figure 4 .
