Patrick,
The monitor signal (Page 16, equation 4) is used to determine, internal to the RDC, the difference in the peak, differential magnitudes at the sine (A1) and cosine (A2) inputs. A mismatch in A1…
Patrick,
The methodology they are using is incorrect. Instead of subtracting COS from SIN they should be using the arithmetic sum and then looking at the peak to peak ripple. If the SIN and COS channels…
Patrick,
Consider by substitution that A1 = 3.2Vpp and A2 = 3.42Vpp as you have entered and that the loop is in steady state such that we can assume for small errors that PHI = THETA and then we can essentially…
