Hi all, I wanted to ask if from a number of bits that are represented with 1 and 0 is possible to invert the ones to -1 each lets say two bits? Thanks in advance.

Not clear to me what do you mean by "from a number of bits" and "to invert the ones to -1 each lets say two bits". Are you saying that if you have an inputs of 10 bits, six 1s and four 0s, alternate randomly, you want to invert the first two 1s into -1?

[1 0]------>Gain(-1)----->[-1 0]
Use the Gain block and define that gain as -1

Ah, instead of a step function, you could perhaps use a Repeating Sequence block, as mentioned at http://www.mathworks.com/matlabcentral/answers/15874-hi-all-i-am-having-a-difficulty-in-switching-a-signal-i-need-a-switch-in-simulink-that-must-be-on
