PDF-Lectur Design of Digital Filters

1 Simple 64257lters There are tw methods for smoothing sequence of numbers in order to approx imate lo wpass 64257lter the polynomial 64257t as just described and the mo ving v erage In the 64257rst case the approximation to LPF c. The following block diagram illustrates the basic idea There are two main kinds of filter analog and digital They are quite different in their physical makeup and in how they work An analog filter uses analog electronic circuits made up from compone Filters in this class are specified by two parameters the cutoff frequency and the filter order The frequency response of these filters is monotonic and the sharpness of the transition from the passband to the stop band is dictated by the filter ord 03 THD or Better Operates from 237V to 8V Power Supplies Low Noise High Frequency 8th Order Butterworth Lowpass Filter The LTC 10642 is a monolithic 8th order lowpass Butterworth filter which provides a maximally flat pass band The attenuation slope Dr .

CICs are an optimised combination of an FIR filter and an interpolator or decimator Require no multiply operations, only addition and subtraction Prof. Kristen . Grauman. UT-Austin. …. Announcements.
