Delta-sigma modulation — Delta sigma (ΔΣ; or sigma delta, ΣΔ) modulation is a method for encoding high resolution or analog signals into lower resolution digital signals. The conversion is done using error feedback, where the difference between the two signals is… … Wikipedia
Time to digital converter — In electronic instrumentation and signal processing, a time to digital converter (abbreviated TDC) is a device for converting a signal of sporadic pulses into a digital representation of their time indices. In other words, a TDC outputs the time… … Wikipedia

Operational amplifier — A Signetics μa741 operational amplifier, one of the most successful op amps. An operational amplifier ( op amp ) is a DC coupled high gain electronic voltage amplifier with a differential input and, usually, a single ended output.[1] An op amp… … Wikipedia
Analog-to-digital converter — An analog to digital converter (abbreviated ADC, A/D or A to D) is an electronic integrated circuit, which converts continuous signals to discrete digital numbers. The reverse operation is performed by a digital to analog converter… … Wikipedia
Integrating ADC — An integrating ADC is a type of analog to digital converter that converts an unknown input voltage into a digital representation through the use of an integrator. In its most basic implementation, the unknown input voltage is applied to the input … Wikipedia
Electronic Flight Instrument System — An electronic flight instrument system, or EFIS, is a flight deck instrument display system in which the display technology used is electronic rather than electromechanical. EFIS normally consist of a primary flight display (PFD), multi function… … Wikipedia
Schmitt trigger — In electronics, a Schmitt trigger is a comparator circuit that incorporates positive feedback.When the input is higher than a certain chosen threshold, the output is high; when the input is below another (lower) chosen threshold, the output is… … Wikipedia
Clinical trial — Clinical trials are a set of procedures in medical research and drug development that are conducted to allow safety (or more specifically, information about adverse drug reactions and adverse effects of other treatments) and efficacy data to be… … Wikipedia
