e at which the total current (. − .) in valve . becomes zero. Figure 5.2 shows how, after the firing of valve ., the current in valve . falls to zero from its original value and the current in valve ., starting from zero, correspondingly increases. The time during which both valves are conducting is measured by the overlap angle ..

Tobias Baer on a transmitter, you are likely to get a blank stare and a question: "Do they make those anymore?" Although receiving tubes have disappeared from the scene, power tubes are alive and well and are performing vital functions in thousands of divergent applications. Solid-state and tube technologies each have t978-1-4684-9989-6978-1-4684-9987-2

applications that work with digital signals analog techniques are still very important for a number of reasons. First the signal that must be processed or stored may be analog at the input and output of the system. Second when digital circuits must operate at high speed the analog behavior becomes

ct current from one current path to another is called commutation and is illustrated in Fig. 5.1, in which the direct current . is to be transferred from the current path comprising valves . and . to the current path of valves . and .. When valve . fires, the short circuit shown by the heavy line is
