In this column, I answer questions about all aspects of electronics, including computer hardware, software, circuits, electronic theory, troubleshooting, and anything else of interest to the hobbyist. Feel free to participate with your questions, comments, or suggestions. Send all questions and comments to: QS-A@nutsvoIts.com Ql found your article on comb filter design to be most interesting! I would like to inquire if you might have a circuit for a comb generator? I'd like it to have equal amplitude marker signals spaced 100 KHz apart, all the way up to 30 MHz. This test generator has multiple uses for calibrating receivers, scopes, etc. Any chance that you might be able to come up with a schematic?
