The Costas Loop and the Best Engineer. By Bill Jones.   This paper is to note some of the work of Dr. John P. Costas and to tell of my work and thoughts of my time with John. He was the best engineer that I have ever known. His work was in a relatively narrow field not well known by most engineers. His work was done starting at General Electric in the early 1950’S and continued over his life time. He contributed greatly to several areas of communications, Sonar and mathematics, for example, the Costas Array. He wrote many papers with some being classic. He continued as an inventor even after his retirement. The term Engineer goes back some years, probably to the 1300’s AD. While I do not mean to compare Dr. Costas to these early genius engineers it should be clear that these early engineers did provide the great foundations we have in our present day curriculums. I am thinking of John as a man that used the foundations to invent an outstanding system - the Costas Loop. If y

A Picture Is Not Worth One Thousand Words .. For immediate release by Thomas Sammon and W. H. Jones   4/1/ 2014     A recent study has been released showing the dimensions of a Pixel as observed by the Eye. The dimension of a Pixel is normally given in inches squared. This is the actual dimension of the Pixel on a flat surface. When the Eye observes the pixel the actual dimensions with respect to the eye are unusual. This subject has not been studied because of the resolution of the eye, and other difficulties involving the shape of the Eye. The Eye is similar to a sphere that is somewhat misshaped.  This paper then defines a usual or Standard Eye which is then given a standard resolution.   When this Standard Eye is defined it then becomes possible to define the actual dimensions of the Pixel with respect to the Eye.  Instead of inches squared the dimensions of the system including the Eye are different from that of a flat surface.  It becomes radians to the power of three divide

About Me - William Haywood Jones I am a scientist in the area of Electrical Engineering, having worked in research and Advanced Development for my entire career. I have worked for companies such as General Electric and Honeywell, and startup companies in Silicon Valley, California. I have designed and built numerous systems both military and commercial. I have designed advanced communications for voice and data. I worked directly with the inventor of the "Costas Loop" for ten years. I designed one of the first "over the horizon" radar systems using Doppler techniques. I worked over fifteen years in the design of computer hard disc drives in the area of read/write. I have ten patents in my areas of engineering. My first patent "W.H. Jones ET AL", Number 2,951,980 was with Dr. J.P.Costas. The patent was used in the first I/Q receiver that was built (AN-FRR-48 XW1). My design work has been from low frequency to high frequency. I am a Professional Enginee

Tube Bias and the Capacitor ~  By Bill Jones   The article is a review of how a tube obtains a negative bias on its grid. Included is a short history of how it has been   done, and   how it should have been done.  Since the capacitor is a major component in the power supply, grid bias, and the radio in general there is a discussion of the capacitor its invention and, application to the power supply because the power supply is often used in obtaining grid bias. When using the power supply for grid bias it generally complicates the circuitry and, adds little to no value to the operation of the radio.   The capacitor is necessary to obtain a “clean” bias from a power supply. Grid bias is very important in the operation of any tube and should always be a consideration in the repair and operation of the radio.  There are some occasions when it may be proper to use the power supply as a grid bias means, but not in the “modern typical radio”.  This will be discussed later. The “mode
