sorry ,my english is poor. I have already tried my best to discription it in english.But I failed. Maybe I will use pictures to ask questions.
Now i just want to say that my dspbuilder is very unstable.Sometimes it can generate FIR without any errors,sometimes it leads to the questions above. What can I do ? ~~~I hope that you can understand my meaning.

Speaking our mother language, Chinese, is very good. Some related English to describe the problem you concerned is needed, too.
