LabVIEW Tools for Digital Filter Design and Implementation

Overview

The NI Digital Filter Design Toolkit extends NI LabVIEW with

comprehensive tools for the design, analysis, and implementation of

both single-rate digital filters and multirate digital filters. Novices can

interactively explore common designs, while experienced users can

select from a comprehensive set of filter types backed by a breadth of

design algorithms, filter topologies, and analysis tools for design,

modeling, and implementation.

An extensive set of more than 75 examples can serve as a starting

point for your floating- or fixed-point designs. For fixed-point filters, you

can model quantization effects and automatically generate ANSI C and

LabVIEW FPGA code for digital signal processing (DSP) or field-

programmable gate array (FPGA) deployment.

The Digital Filter Design Toolkit also offers sets of LabVIEW

MathScript filter design functions for users who are accustomed to

text-based filter design.

Digital Filter Selection

The first stage of digital filter design involves selecting an appropriate

filter type for your application. The Digital Filter Design Toolkit offers

more than 30 types of filters that are useful in a variety of applications

such as those presented in Table 1.

To specify and design a filter, the toolkit includes Express VI-based

interactive tools for classical filter designs and design through

placement of poles and zeros. As you modify parameters, the interface

immediately shows the magnitude response and pole-zero locations on

the Z-plane based on your selections. Using the pole-zero design tools,

you can click and drag poles and zeros for placement on the Z-plane.

You can also programmatically design these and other filter types with

included LabVIEW programs (VIs) that are easily wired into LabVIEW

diagrams. The toolkit includes a comprehensive variety of more than

25 design algorithms ranging from classical (Butterworth, Chebyshev,

window, and so on) to modern optimizing options including Remez

exchange (for arbitrary magnitude FIR filters and multirate filters) and

least Pth norm (for arbitrary magnitude and phase FIR/IIR).

Filter Type Example Application

FIR bandpass Extract a radio station from a broadband radio signal

Comb Separate luminance and chrominance components

from a composite TV signal

N-stage multirate Resample a signal to increase or decrease the sampling

rate of a signal by a factor that is a rational fraction

Group delay compensator (allpass) Reduce phase distortion that occurs after applying

a filter with a nonconstant group delay

Raised cosine For a digitally modulated signal, limit the occupied

bandwidth and reduce intersymbol interference
