I wrote method of evaluation of THD in the following as Ocean Script. http://www.designers-guide.org/Forum/YaBB.pl?num=1237208147/1#1 What is "IIM3" ? Did you read answers to your questions surely ? http://www.designers-guide.org/Forum/YaBB.pl?num=1237208368/1#1 http://www.designers-guide.org/Forum/YaBB.pl?num=1237293628/1#1 Read documentations.

Did you follow oermens's advice surely ? http://www.designers-guide.org/Forum/YaBB.pl?num=1237293628/1#1 I think you don't read documentations at all. Read documentations surely. david wrote on Mar 18th, 2009, 11:58am:

If we read your sentences where almost all terminologies are wrong or improper, it is very obvious that you are new to everything. david wrote on Mar 18th, 2009, 11:36pm:
Read, Read and Read documentations with cutting down your sleeping time. If you are lack of ability of understanding documentatios quickly, attend trainings provided by Cadence which are charged not free. |
Title: Re: THD calculation Post by david on Mar 19th, 2009, 9:02am thank you for your reply . I started reading cadence help documents. now i am able to calculate THD values. I know there are no shortcuts but actualy I didnt know how to use cadence help documents that is why i was wondering about tool usage and hence asked such questions. anyways thanks again for your replies |
