The approximation problem of network synthesis is considered
in four parts. First, the problem is identified. Second, the several
existing methods of solving this problem are briefly discussed. This
discussion is necessary because the well known methods have inherent
limitations if they are to be ultimately applied to the other...
This thesis deals with the problem of realizing
filter and delay functions by means of an active network
structure composed of distributed RC networks in
conjunction with a negative-impedance converter. Presented
is a general synthesis technique which can be
used for the realization of rational filter and delay
functions such...
A method for the synthesis of networks with specified complex
terminations is presented. The specification function is realized
within a multiplicative constant. The technique presented differs
somewhat from present methods employed in the synthesis of networks
with resistive terminations.
The technique is one of rearranging a transfer function and
separating...
This paper is a study of the procedures used in achieving element
reduction in networks realized from a given network function.
Reduction in the number of elements in RC-realization is possible
in the synthesis of a transfer function and in the simultaneous realization
of driving-point function and a transfer function,...
The paper is a study of (i) the realization of the gyrator,
(ii) active filter synthesis using gyrator.
Several realization methods of the gyrator are summarized.
A practical gyrator composed of two operational amplifiers was built
and tested. The experimental results are shown. Two RC-gyrator
synthesis techniques are derived and...
In this thesis, we are concerned with the synthesis of a
specified voltage ratio transfer function having a specified complex
termination. A method for the active network synthesis with specified
complex termination using resistive and capacitive elements and only
one negative impedance converter is presented. The synthesis
technique involves rearranging...
Active transmission lines, a generalization of classical transmission
lines, are useful electrical devices. They can be utilized to
realize distributed amplifiers and to obtain other electrical characteristics unattainable with passive lines. Active lines have historical
significance and model many physical processes including heat
conduction in an internally heated material, a...
In the first part, two classes of rational approximation of ideal
delay function e[superscript]⁻s (Bessel and Binomial) are studied and the step
responses of both approximations are compared. Hazony's RC-active
delay circuit for different values of k are investigated. The comparison
of the step responses of this circuit and the...
A circuit which functions as a controlled negative-resistance is
described and analyzed; the circuit contains two transistors, a breakdown
diode, and five resistors connected in a stable feedback configuration.
From the analysis a set of design equations is derived.
An experimental circuit is described and a comparison between
measured performance...
