Aliasing occurs when anoscilloscopedoes not sample the signal fast enough to construct an accurate waveform record. The signal frequency is misidentified, and the waveforms displayed on an oscilloscope become indistinguishable. Aliasing is basically a form of undersampling. The undersampled waveform is ...
Aliasing is characterized by the altering of output compared to the original signal because resampling or interpolation resulted in a lower resolution in images, a slower frame rate in terms of video or a lower wave resolution in audio. Anti-aliasing filters can be used to correct this problem....
Signal filtering (e.g. anti-aliasing filtering) Conformance with sensor requirements. We will now look at each of these elements of signal conditioners. Check outDewesoft's data acquisition systemswhich offer high-end signal conditioning for any sensor. ...
Signal processing is used in order to analyse measured data. Read the article to learn how signal processing is performed and applied in DAQ applications.
In addition to digital imaging, aliasing can occur in other contexts, such as digital audio. In this field, aliasing refers to the distortion that arises when a signal’s frequency is underestimated because of an inadequate digital sampling rate. To prevent aliasing in digital audio, recording wi...
In analog-to-digital converters (ADC), the analog signal must be processed before it is converted into a digital signal. This usually includes current or voltage limiting and anti-aliasing filtering (AAF). Current/voltage limiting means that the current/voltage is limited to a certain level to...

(inter-sample peak) limiting. These algorithms retain the punch of your master while minimizingdistortionand overloads when the digital signal converts to analog or to a lossy digitalcodec, like mp3. Many maximizer plugins also provide oversampling options to avoid digital aliasing distortion. See...
CompactRIO with NI-DAQmx brings two software experiences into one by combining the ease of use of NI-DAQmx and the low-level functionality of LabVIEW FPGA.
