Perhaps it would be opportune to mention my book:
Excel by Example: A Microsoft Excel Cookbook for Electronics Engineers
published by Elsevier/Newnes ISBN: 0750677562
Amongst many other functions pertinent to electrical engineering, I also
describe the sine function

Start with Excel's Help menu. Look up or search for the SIN()
worksheet function.

So yo are designing a 'UPS control with PID' but ar unable to find the
sine function in excel? Interesting skills set.

Hi Mr.JM,
can you please help me to create sine lookup table using excel.I dont
know how to create in excel.

Assuming you mean DAC (not adc), write a simple program in your
favorite language to spit out source code in whatever language you are
using to program your micro.

Hi,
Can anyone guide me to create a sine lookup table according to the adc
value.I am new to PIC.so plz help me.
I am designin a UPS control with PID.here sine wave is generated according
to the adc and triangle wave is generated with fixed amplitute.
Then these two will compare by comparator.
Plz tell me how to do this task.....
