INTRODUCTION
function by decomposing it into a weighted sum of much simpler sinusoidal component functions sometimes referred to as normal Fourier modes, or simply modes for short. The weights, or coefficients, of the modes, are a one-to-one mapping of the original function. These modal coefficients are sometimes themselves confusingly referred to as modes for brevity, especially in physics literature. Fourier series serve many useful purposes, as manipulation and conceptualization of the modal coefficients are oft ....etc

Abstract Test card for color TV is a widely used method to evaluate the quality of a TV set directly. We have made a test signal generator (which can also generate synchronizing (abbreviated to sync hereafter) signals) mainly based on microprocessor Z-80. Taking the advantage of microprocessor programming, combining with the technique of microprocessor, digital circuits and analogue devices, we use software as far as possible to generate signals directly or to simplify the controlling circuits. Those signals, such as composite sync signal, bla ....etc

ABSTRACT

New technique for two-dimensional (2-D) spectral estimation of a stationary random field (SRF) is investigated in this paper. This is based on the extension of the Radon transform theory to stationary random fields (SRF’s), proposed by Jain and Ansari . Using the Radon transform, the 2-D estimation problem is reduced to a set of onedimensional (1-D) independent problems, which could then be solved using 1-D linear prediction (LP) or by any other high ....etc

ABSTRACT
Hyper spectral imaging, or imaging spectroscopy, combines the power of digital imaging and spectroscopy. For each pixel in an image, a hyper spectral camera acquires the light intensity for a large number of contiguous spectral bands. Every pixel in the image thus contains a continuous spectrum and can be used to characterize the objects in the s ....etc

What is Spectral density??
Spectral density is a positive real function of a frequency variable associated with a stationary stochastic process, or a deterministic function of time.
Spectral density has dimension of power per HZ or energy per HZ.
The spectral densities are flat, i.e. independent of frequency.
Flat spectral density:-
• Spectral density is often called the spectrum of the signal .
