NI 9361 Datasheet - National Instruments
www.ni.comProgrammable Digital Filter The NI 9361 has a digital filter on each of the digital input lines to filter unwanted glitches on the digital input signal. You can configure the following filter properties for each of the input lines: • Enable or disable the digital filter. • Minimum pulse width of the input signal that passes through the filter.
INTRODUCTION TO DIGITAL FILTERS
www.physics.csbsju.eduDigital filters are easily designed, tested and implemented on a general-purpose computer or workstation. 3. The characteristics of analog filter circuits (particularly those containing active components) are subject to drift and are dependent on temperature. Digital filters do …

INTRODUCTION TO DIGITAL FILTERS - Physics 123/253
123.physics.ucdavis.eduAt all stages, the signal being filtered is an electrical voltage or current which is the direct analogue of the physical quantity (e.g. a sound or video signal or transducer output) involved. A digital filter uses a digital processor to perform numerical calculations on sampled values of the signal.

Design of Digital Filters
web.eecs.umich.eduDesign of FIR Filters An FIR lter of length M is an LTI system with the following difference equation1: y[n] = MX 1 k=0 bk x[n k]: Note that the book changes the role of M here. Earlier, when discussing rational system functions, M was the number of zeros. Now M is the number of finonzerofl elements of h[n], which corresponds to at most M 1 ...

Sigma-Delta ADCs and DACs - Stanford University
ccrma.stanford.eduThe design of a fifth-order sigma-delta modu lator (as in the AD1879 duall8 bit ADC) is certainly not a trivial matter, and neither is the digital filter. The sigma-delta converter is inherently an oversampling converter, although oversampling is just one of the techniques contributing to the overall per formance.
