Voltage Reference Elements, conditions. All circuits are, to a greater or lesser extent, sensitive to supply voltage variations. In extreme cases these may cause catastrophic malfunction of the circuit ; more usually the accuracy, noise level or fidelity of the circuit is affected. When the circuit itself presents a varying l

Selenium Rectifiers, a variety of applications. Since their original practical realisation the basic structure has remained unchanged, improvements being generally in methods of manufacture and processing which have resulted in improvements in yield, voltage rating, current rating, operating temperature, reliability an

Semiconductor Control Devices,gative resistance makes possible the design of unique switching circuits comprising fewer components than comparable transistor circuits. The input impedance of the UJT in the off state is high— in the order of 5 megohms — making the UJT suitable for high input impedance voltage sensing circuits.

Auxiliary Circuit Elements,silicon content and electrical properties and the grades are known by various trade names Table 1 gives a cross-reference guide to typical properties and trade names. Some of these names are now obsolete but are included for reference.

Single-Phase Rectifiers, for a multitude of applications. High power requirements usually adopt polyphase rectifiers to provide an even loading of the generating equipment and low ripple. Far greater in number, however, are the uses of the low power single-phase rectifier. These are found in great abundance in both industr

DC Stabilisers,15% when mains changes, regulation and ageing effects are taken into account. Although it is difficult to imagine a case where it would be impossible to design a circuit that would not continue to function with supply variations of this order, it is fairly easy to demonstrate that circuit performanc
