The anti-aliasing filter incorporated in the output refinement stage can be any desired analog or digital filter with the appropriate cutoff corresponding to the chosen output rate.
Developed sensory system consists of microphone array with 15 omnidirectional condenser microphones with optimised geometry for frequency range of 1500 Hz to 2000 Hz and 16 channel preamplifier combined with anti-aliasing filter. Evaluation system is represented by standard personal computer equipped with multifunction DAQ card Advantech PCI-1716 with 16 analog input channels.
After amplifier stage is connected 4th order low-pass filter designed using Bessel approximation which function as anti-aliasing filter with cutoff frequency of 20000Hz.
This compensates for the effect of a new anti-aliasing filter that tends to soften images.
To protect against this phenomenon, an anti-aliasing filter is applied to the data at one half of the sampling frequency.
Indeed, some data acquisition systems operate with a fixed high sampling rate well above the system bandwidth that allows a relatively low-cost, low-order analog anti-aliasing filter to be used.
* Anti-aliasing filter. Attenuates signals outside the band of interest.
Any filter placed in the analog signal input stream to an A/D converter is often referenced as an "anti-aliasing filter." In many cases this is not an accurate description.
These applications require an anti-aliasing filter. These typically are 4-pole or greater filters set at one-half the sample rate.
In Part 2 of the article--appearing online at ecnmag.com (click on "Current Issue"), the three main blocks that form the heart of a digital controller will be discussed--an anti-aliasing filter, an analog to digital converter (ADC), and a digital pulse width modulator (DPWM), as depicted in Figure 2.
