Abstract

This paper addresses the equations necessary to evalute the required sampling frequency as a function of the ratio of amplitudes between the clock frequencies and the frequencies that are modulated onto the respective clock frequencies. A key ingredient that is also involved in the appropriate selection of the sampling frequency is the base band noise level that is indicated for each of the channels that are provided in the protocol from the information providers. By using the technique was associated with thermal signature and imaging processing, one is able to use a multiplicity of fast fourier transforms to subtract out images from background and noise and to recreate the image in a clean and noise free environment. In so doing one is able to maintain the image without subjection to outside disturbance or distress.
