Signal Adapters include circuit board to process wired TV signal and telephone signal from coaxial cable. These wired TV signals and telephone signals are transmitted from a coaxial cable to the circuit board. The main signal output port through which wired TV signal and telephone signal are transmitted from the circuit board to a next signal adapter.

Signal Analyzers employ digital techniques of signal analysis to extract useful information that is carried by the signal. The common procedure used is digital fourier analysis using fast fourier transforms. Fourier analysis produces the frequency spectrum of a time signal. It has two or more input signal channels. To generate results such as frequency response functions, cross spectra, coherence functions and cross-correlation functions dual-channel analyzer is used.

A signal conditioner is a device that converts one type of electronic signal into another type of signal. Its primary use is to convert a signal that may be difficult to read by conventional instrumentation into a more easily read format. In performing this conversion a number of functions may take place. They include amplification, electrical isolation, linearization, cold junction compensation and excitation. These are used to isolate signals, convert signals, or provide a common interface to a control and monitoring system.

Signal Conditioning Modules are used for the coupling and transformation of physical signals from the process periphery into a form that is suitable for the microcontroller.

A signal integrity analysis is a program that performs the electromagnetic field simulation and the circuit simulation is introduced in this paper. The electromagnetic field simulation algorithms are based on special geometric features of packaging structures and can run two to four orders of magnitude faster than general-purpose electromagnetic tools. The use of the distributed circuit simulation technique drastically reduces the simulation time for lumped circuit components. This analysis can promptly simulate practical packages of tens of power/ground planes and thousands of vias and signal traces, while considering signal integrity problems such as signal delay, distortion, reflection, coupling, and power/ground noise. The accuracy of the simulated results is verified by measurements.
