Removing ^D and ^H characters

Hi,

I have a very huge file and it contains some unprintable characters like ^H and ^D.

If I try to remove using cat test1.ser| tr -d '\136 110'>newfile1 it is only removing ^and all spaces in the file.

How can I remove these characters (^D ^H) and keep my spaces as it is?

Thanks & Regards
Shesha
