Filters

This webpage contains some notes and comments on filters I have gleaned from my experiences in ham radio and commercial service, working in a microwave design group, working in land mobile infrastructure, and working in cellular infrastructure. One thing I have learned in more than 25 years in the electronics business ... I don't know everything ... but I do know some things. So read, ponder, learn, question, comment, correct ... and enjoy.
