I am calculating power factor from samples of voltage and current. Calculation is done by multiplying voltage and current samples. What Im struggling is sign. I have read it is possibleto determine sign with JK negative triggered flip flop method. I found how exactlly JK flip flop works but still Idont get it how to get sign from it.
