  2. Signal conditioning - Wikipedia

    en.wikipedia.org/wiki/Signal_conditioning

    In electronics and signal processing, signal conditioning is the manipulation of an analog signal in such a way that it meets the requirements of the next stage for further processing. In an analog-to-digital converter (ADC) application, signal conditioning includes voltage or current limiting and anti-aliasing filtering .

  3. Data acquisition - Wikipedia

    en.wikipedia.org/wiki/Data_acquisition

    A data acquisition system is a collection of software and hardware that allows one to measure or control the physical characteristics of something in the real world. A complete data acquisition system consists of DAQ hardware, sensors and actuators, signal conditioning hardware, and a computer running DAQ software.

  4. Digital-to-analog converter - Wikipedia

    en.wikipedia.org/wiki/Digital-to-analog_converter

    8-channel Cirrus Logic CS4382 digital-to-analog converter as used in a sound card.. In electronics, a digital-to-analog converter (DAC, D/A, D2A, or D-to-A) is a system that converts a digital signal into an analog signal.

  5. Time-to-digital converter - Wikipedia

    en.wikipedia.org/wiki/Time-to-digital_converter

    During the transition of the start signal through one of those cells, the signal is delayed by and the state of the flip-flop is sampled as transparent. The second delay line belonging to the stop signal is composed of a series of non-inverting buffers with delay <. Propagating through its channel the stop signal latches the flip-flops of the ...

  6. Compressed sensing - Wikipedia

    en.wikipedia.org/wiki/Compressed_sensing

    An early breakthrough in signal processing was the Nyquist–Shannon sampling theorem. It states that if a real signal's highest frequency is less than half of the sampling rate, then the signal can be reconstructed perfectly by means of sinc interpolation. The main idea is that with prior knowledge about constraints on the signal's frequencies ...

  7. Frequency counter - Wikipedia

    en.wikipedia.org/wiki/Frequency_counter

    Most frequency counters work by using a counter, which accumulates the number of events occurring within a specific period of time.After a preset period known as the gate time (1 second, for example), the value in the counter is transferred to a display, and the counter is reset to zero.

  8. Digital signal conditioning - Wikipedia

    en.wikipedia.org/wiki/Digital_signal_conditioning

    Digital signal conditioning in process control means finding a way to represent analog process information in digital format. [2] Use of in control system is particularly valuable number of other reasons, however: A computer can control multivibrator process-control system. Nonlinearities in sensor output can be linearized by the computer.

  9. Analog front-end - Wikipedia

    en.wikipedia.org/wiki/Analog_Front-End

    Atheros Intellon 1200 AFE-Chip as companion for an INT 5500 PowerLine-IC. An analog front-end (AFE or analog front-end controller AFEC) is a set of analog signal conditioning circuitry that uses sensitive analog amplifiers, often operational amplifiers, filters, and sometimes application-specific integrated circuits for sensors, radio receivers, and other circuits to provide a configurable and ...
