This value is nominally 180eC360°ePulse Width Error(AP): The deviation of pulse width, inP(180e)electrical degree, from its ideal value of 180eState Width(S): The number of electrical degrees between a transition in theoutput of channel A and the neighbouring transition in the output of channelhannel AB. There are 4 states per cycle, each nominally 90ePhase( p): The number of electrical degrees between the centre of the highp(90°e)state of channel a and the center of the high state of channel B.
