.~ Transformer or resonant circuit in interstage coupling (e.g., stagger tuning)
DEFINITION
Classification: 330/154
(under subclass 152) Subject matter wherein at least one of the interstage coupling means has a signal coupling transformer or a resonant circuit contained therein.
(1) Note. Stagger tuned amplifiers are classified in this subclass.
