Like I said, draw a diagram - it's easy - heres an example, top two are the two input waveforms, bottom one the output from an XOR. The bottom waveform is a direct representation of the phase difference.
Dear Nigel,
I am so so thankful to you for explaining this to me in such a detail.
As u have suggested me to draw a few cases, I have attached a diagram where I have assumed two cases of delayed signal [named as signal2]. As far as I could imagine [I might be wrong] that if we take a reference point on signal [signal1] on the rising edge of the pulse, the delay signal will possibly have the two cases:
1) if signal2 arrives as low = that means 0-180 deg delay &
2) if signal2 arrives as high = that means the delay signal [signal2]has
crossed the 0-180 deg of delay range and now
it's in 180-360 deg range.
In the attached diagram, I have taken two such cases, one for 10 deg delay and second one is for 350 deg delay and I have found out that the output pulse from XOR gate has the same pulse width.
Now that implies that for any delay value [in deg] between 0-180 [say 'x'] will have the same value for the signal with a delay of 360-x deg[ In my case,10 deg will be same as 360-10 =350 deg]. I am all confused about how to calculate the phase on these cases??
I apologise Nigel if I have over thought it but I would really appreciate any further help on this matter.
Thank you soo soo much .
Ps: I apologise if the diagrams are not upto the scale.
