Some Little-Known Facts About Transmission Lines and Some New Results
The study of transmission lines forms an integral part of any curriculum in electrical engineering. This paper presents some little-known but interesting facts about transmission lines, which are generally not found in textbooks, along with some new facts, which arose as extensions of these little-known ones. The facts highlighted in this paper are that: 1) the real part of the characteristic impedance is always greater than the magnitude of its …
On digital differentiators, Hilbert transformers, and half-band low-pass filters
Interrelationships between the digital differentiator (DD), the digital Hilbert transformer (DHT), and the half-band low-pass (1/2-LPF) are brought out. A number of important properties confirming the close proximity of these filters are highlighted. Theoretical results are substantiated by transforming minimax relative error DDs to equiripple DHTs and equiripple 1/2-LPFs. Relations connecting their impulse responses and their frequency responses…
On a Theorem Used in Determining a Driving-Point Immittance from Its Phase Specifications
A simple and straightforward proof is given of the following theorem: The slope of the numerator polynomial of the odd part of a positive real function F(s) is negative at a pole, and positive at a zero, of F(s) on the imaginary axis, including the origin. The theorem is used in the tangent function method of deriving a drivingpoint immittance from the specification of its phase
Impedance Measurement by a Resistive Bridge
The possibility of measuring an unknown impedance Z=R+jX by including it in one arm of a Wheatstone bridge, whose other arms are purely resistive, is examined. It is shown that by adjusting the variable resistance for minimum bridge output and measuring this output, one can calculate the magnitude |Z|, the resistive part R, and the magnitude of the reactive part |X| of the unknown impedance. Using a fixed auxiliary capacitor whose reactance is le…
