The Π pad (pi pad) is a specific type of attenuator circuit in electronics whereby the topology of the circuit is formed in the shape of the Greek capital letter pi (Π). Attenuators are used in electronics to reduce the level of a signal. They are also referred to as pads due to their effect of padding down a signal by analogy with acoustics ...
An attenuator is a passive broadband electronic device that reduces the power of a signal without appreciably distorting its waveform. An attenuator is effectively the opposite of an amplifier, though the two work by different methods. While an amplifier provides gain, an attenuator provides loss, or gain less than unity. An attenuator is often ...
The interface features a Kansas City standard Compact Cassette interface and printer port for the FP-10 thermal printer. The printer can also be connected directly to the calculator. The FP-10 Spark printer was used with the FX-602P series of programmable calculator and the FX-702P Pocket Computer to print out programs, data register and ...
The Calculator in non-LTSC editions of Windows 10 is a Universal Windows Platform app. In contrast, Windows 10 LTSC (which does not include universal Windows apps) includes the traditional calculator, but which is now named win32calc.exe. Both calculators provide the features of the traditional calculator included with Windows 7 and Windows 8.x ...
Attenuation is an important consideration in the modern world of wireless telecommunications. Attenuation limits the range of radio signals and is affected by the materials a signal must travel through (e.g., air, wood, concrete, rain). See the article on path loss for more information on signal loss in wireless communication.
HP-45 Windows Phone 7 App An Emulator for Windows Phone 7. HP-45 Emulator in JavaScript The HP-45 Program ROM was translated to JavaScript to have an exact simulation of the original calculator for use in web browsers. HP-45 Emulator in Python Simulates the HP-45 and displays and explains its inner workings.
In mathematics, Machin-like formulas are a popular technique for computing π (the ratio of the circumference to the diameter of a circle) to a large number of digits.They are generalizations of John Machin's formula from 1706:
Built-in variable optical attenuators may be either manually or electrically controlled. A manual device is useful for one-time set up of a system, and is a near-equivalent to a fixed attenuator, and may be referred to as an "adjustable attenuator". In contrast, an electrically controlled attenuator can provide adaptive power optimization.
