Abstract: The CMOS active pixel sensor (APS) operating in the logarithmic mode is the most common and useful CMOS wide-dynamic-range imager. Notwithstanding, fixed-pattern noise (FPN) between pixels ...

Abstract: This brief utilizes the logarithmic number system (LNS) to realize the half-precision division (DIV), square root (SR), and inverse SR (ISR) that are widely ...

Logarithms are everywhere in mathematics and derived fields, but we rarely think about how trigonometric functions, exponentials, square roots and others are calculated after we punch the numbers into ...

Logarithms, often referred to as “logs,” are a fundamental concept in mathematics that allow us to express the relationships between exponential quantities. Logarithms are especially useful in ...

Add a description, image, and links to the elliptic-curve-discrete-logarithm topic page so that developers can more easily learn about it.

Vector graph or chart of logarithmic function with formula y = log x, fx = ln x. Logarithm, inverse function to exponentiation. Mathematical operation, basic function. Graph with grid and coordinates.

A logarithm is a mathematical operation that determines how many times a certain number, called the base, is multiplied by itself to reach another number. Because logarithms relate geometric ...

You may find this hard to believe, but there are people still alive today who once did their mathematical calculations by sliding sticks back and forth. No keypads, no batteries, no LEDs. Just sticks.

I. Basic logarithms. Radio Frequency (RF) power is measured in milliwatts (mW) or -- more usefully -- in a logarithmic scale of decibels (dB), or decibels referenced to 1 mW of power (dBm). Since RF ...

There was a time not so long ago when calculators weren’t standard equipment for computations. The log() button did not exist, and some math had to be done by hand. John Napier and his logarithm ...
