Hi Steve,
Thanks for your reply and extremely sorry for my delayed response I am stuck with some work and hence couldn't respond. Once again, it all comes down to just how good you want it to be. What is the maximum permissible error you can accept, and where does it come from ? It comes from resistor temperature drift, amplifier drift etc. etc. If your final accuracy is 10% you have no problems, and a high impedance resistive divider off the coil will tweak the result nicely. If your final accuracy is 1%, then you will need to think very carefully about all the things mentioned above. You are right Steve I will have to take into account the error sources and the resultant error due to such factors before finalising on a specific method. I agree with you and steve the seeprom method is the better one and is resistant to drifts and related errors. Thanks & Regards, Prahlad Purohit |
