Hi all Anyone got any suggestions as to how to put together a 5MHz sawtooth generator, I'd really like something quite linear and adjustable if possible, can't see any simple chip solutions out there so looking for a bit of advice. Its for playing with a FMCW radar module if anyone is interested Cheers Ed -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
