Abstract
Official abstract text for this publication.
A design for a Tunable Cable Simulator with a minimum number of components and low insertion loss.
First claim
Opening claim text (preview).
We claim: 1. An apparatus for modifying a coaxial cable signal, comprising: a circuit installed between two coaxial cables, the circuit further comprising: an input; an output; an upper portion comprising an inductor, a capacitor, and a first variable resistor; a lower portion comprising a second variable resistor, a third variable resistor, and one variable capacitor; a microprocessor; and a table comprising one or values configured for programming the first, second, and third variable resistors and the variable capacitor, wherein the table is stored in the microprocessor; wherein the first, second, and third variable resistors and the one variable capacitor can be programmed to the values stored in the table on the microprocessor to effect tuning of the cable signal to simulate 0 to about 18.5 dB cable response; wherein the inductor, capacitor, and first variable resistor are connected in parallel between the input and the output, and wherein the variable capacitor is connected between the second and third variable resistors, and wherein the variable resistors and the variable capacitor work to achieve a constant impedance across a cable line.
