Improvements in Regenerative Frequency Dividers

This report describes novel regenerative frequency dividers where the use of multiple-tuned circuits In the mixer or multiple-tuned circuits In conjunction with crystal rectifier distorters provide a number of advantageous operating characteristics with a minimum number of tubes. The particular circuits have a high division ratio, require no voltage-regulated power supplies, and exhibit self-starting and locking qualities heretofore not available with regenerative frequency divider techniques.
