Design of linear electrical networks to produce waves of given shape from impressed square waves.

The thesis first examines, briefly, work previously done by othersin producing electrical waves of preassigned shape. Then afterdiscussing the relation between square waves and those of differentsimple forms, the distinction between individual pulses and trainsof pulses is pointed out. The transient and steady state responsesof linear passive networks are next considered, and the connectionbetween input and response analyzed. Finding such a network toproduce the desired wave shape from a given input is reduced to twogeneral methods.The first method is a deductive one, reducing the required networkcharacteristics to design parameters, for a graphical synthesisprocedure. This is described in a general way only.The second method is an inductive or empirical one, based oncataloguing the responses obtained by applying a given input, atdifferent fundamental frequencies, to various networks. The procedureis illustrated experimentally and analysed mathematicallyfor simple cases. A scheme of classifying complex wave shapes isalso proposed.Some limitations of the two methods are indicated with suggestionsfor future study. A comprehensive bibliography of articles relatingto the subject is appended
