51Voltage divider — In electronics, a voltage divider (also known as a potential divider) is a simple linear circuit that produces an output voltage ( V out) that is a fraction of its input voltage ( V in). Voltage division refers to the partitioning of a voltage… …
52Luhn mod N algorithm — The Luhn mod N algorithm is an extension to the Luhn algorithm (also known as mod 10 algorithm) that allows it to work with sequences of non numeric characters. This can be useful when a check digit is required to validate an identification… …
53Phase-locked loop — PLL redirects here. For other uses, see PLL (disambiguation). A phase locked loop or phase lock loop (PLL) is a control system that generates an output signal whose phase is related to the phase of an input reference signal. It is an electronic… …
54Switched-mode power supply — switched mode power supply. A bridge rectifier B Input filter capacitors C Transformer D output filter coil E output filter capacitors ] A switched mode power supply, switching mode power supply or SMPS, is an electronic power supply unit (PSU)… …
55Productivity — in economics refers to measures of output from production processes, per unit of input. Labor productivity, for example, is typically measured as a ratio of output per labor hour, an input. Productivity may be conceived of as a measure of the… …

57Sensitivity analysis — (SA) is the study of how the variation (uncertainty) in the output of a mathematical model can be apportioned, qualitatively or quantitatively, to different sources of variation in the input of a model Saltelli, A., Ratto, M., Andres, T.,… …
58Electronic amplifier — A practical amplifier circuit An electronic amplifier is a device for increasing the power of a signal. It does this by taking energy from a power supply and controlling the output to match the input signal shape but with a larger amplitude. In… …
59Cooley–Tukey FFT algorithm — The Cooley–Tukey algorithm, named after J.W. Cooley and John Tukey, is the most common fast Fourier transform (FFT) algorithm. It re expresses the discrete Fourier transform (DFT) of an arbitrary composite size N = N1N2 in terms of smaller DFTs… …
