Title: Electronic, frequency control start circuit - prevents faulty energising of flip=flop, energised at corresp. side from negative circuit output
Inventor: MERKLE PAUL
IPC: H03K5/1252
Filed: 1990-05-18
Abstract: The circuit is designed as a starting circuit for frequency controls, and does not transmit the first pulse or the residue pulse.
