Accuracy And Precision
Accuracy and precision are two measures of ''observational error''. ''Accuracy'' is how close a given set of measurements ( observations or readings) are to their ''true value'', while ''precision'' is how close the measurements are to each other. In other words, ''precision'' is a description of '' random errors'', a measure of statistical variability. ''Accuracy'' has two definitions: # More commonly, it is a description of only '' systematic errors'', a measure of statistical bias of a given measure of central tendency; low accuracy causes a difference between a result and a true value; ISO calls this ''trueness''. # Alternatively, ISO defines accuracy as describing a combination of both types of observational error (random and systematic), so high accuracy requires both high precision and high trueness. In the first, more common definition of "accuracy" above, the concept is independent of "precision", so a particular set of data can be said to be accurate, precise, both, ...

Precision Monolithics
Precision Monolithics, Inc. also known as PMI, was an American company based in Santa Clara, California, that developed and produced mixed signal and linear integrated circuits (ICs). It was a pioneer in the fields of digital-to-analog converters and operational amplifiers. The company was founded in 1969 by Marv Rudin and Garth Wilson, who had both left Fairchild Semiconductor at the end of 1968. Wilson was circuit design manager under Rudin, who managed linear circuit R&D at the Fairchild Semiconductor R&D Laboratory in Palo Alto from 1966 to 1968. At the beginning, Wilson was vice president responsible for engineering and production, and reported to Rudin, who was president and marketing manager. Jim Grugan from Fairchild joined shortly after incorporation as vice president of administration, responsible for finance, facilities and purchasing. Immediately after financing and incorporation, they offered founder stock and hired IC designers George Erdi from Fairchild and Dan Doo ...

Fender Precision Bass
The Fender Precision Bass (often shortened to "P-Bass") is a model of electric bass guitar manufactured by Fender Musical Instruments Corporation. In its standard, post-1957 configuration, the Precision Bass is a solid body, four-stringed instrument usually equipped with a single split-coil humbucking pickup and a one-piece, 20-fret maple neck with rosewood or maple fingerboard. Its prototype, designed by Leo Fender in 1950, was brought to market in 1951. It was the first electric bass guitar to earn widespread attention and use, remaining among the best-selling and most-imitated electric bass guitars with considerable effect on the sound of popular music. Background The double bass is among the largest and most physically cumbersome instruments which are regularly still transported by the player themselves on their own. It is also hard to hear in large bands or those that use amplified instruments, and it requires specialized skills to play that are distinct from those requir ...
