Match Document Document Title
4565975 Synchronization of pull-in oscillators in the transmission of digital signals  
Transmission lines for digital signals may include a large number--for example, several hundred--of intermediate generators. In this case, telemetering units are provided at the end points and at...
4114111 Constant phase delay network having a coherent reference  
The delay elements of a signal energy transmission network are divided into separate portions through which the transmitted energy is phase shifted by substantially equal amounts. A phase...
3757244 PHASE LOCKED LOOP WITH NON-LINEAR FILTER RESPONSIVE TO ERROR SIGNAL AMPLITUDE  
For use in pulse timing recovery and other applications, a phase locked loop is proposed having a nonlinear network in which both gain and bandwidth are functions of the eror signal amplitude. The...
3751686 TELEGRAPH RELAY  
A solid state telegraph relay of the dual channel type is provided in which each signal channel output is constrained to OPEN and CLOSE as a function of the differential between the strengths of...
