By the addition of suitably chosen reactive elements the amplitude, phase, and time responses of the network will be improved. A five reactive network with three terminals is analyzed on a normalized basis and compared to the simple RC network which will be called the uncompensated reference. Two capacitive elements in the network represent the division of the distributed parasitic capacitive% into lumped elements while the remaining three elements are physical entities. Values for the reactive elements will be selected for three different criteria: 1) critically damped transient response, 2) maximally flat amplitude response, and 5) linear phase response. After the parameters have been selected the normalized equations for amplitude, time delay, and step response will be derived and plotted for comparative purposes. Pole-zero plots are also drawn to give a more succinct picture of the networks analyzed. The calculations for this report were made with either an IBM 650 computer or a desk calculator. Six significant figures were maintained in the calculations. However, all figures in this report will be rounded off to four places.Read More
