* Crystal rectified D, obviously, can be replaced by a two-electrode or three-electrode vacuum valve, or by a battery of valves if desired. The system of Figure 45 is applicable to the reception of damped or undamped oscillations. 32. SIMPLE REGENERATIVE CIRCUIT. The circuit shown in Figure 46 has been much used for the reception of damped and un- damped oscillations. It is merely an elaboration of that shown in Figure 43a. A point of departure from other systems is the method of connect- ing t...he terminals of the secondary coil L-2 to the valve. One terminal connects through the grid condenser C to the grid G, and the opposite terminal to the plate P. There has been much argument concerning the functioning of this circuit, but careful scrutiny reveals that the grid and plate circuits are electrostatically coupled through condenser C-2. Ad- ditional magnetic coupling is afforded through coils L-3 and L-4, but as first used, the condenser (7-2 provided the entire regenerative coupling. The inductive coupling permits a greater amount of energy to be sup- plied to the grid circuit by the plate circuit, and is useful for giving *This, of course, is true of all regenerative circuits.
