FDATool provides access to most FIR and
IIR filter design methods in the toolbox.
Additionally, you can:
• Design filters by graphically placing poles
and zeros in the z-plane
• Analyze filters by examining magnitude,
phase, impulse, and step responses, group
delay, and pole-zero plots
• Generate C header files
• Import designed filters and filter
coefficients stored in the MATLAB
workspace and export filter coefficients
• Access additional filter design methods and
quantization features in the Filter Design
Toolbox (available separately)
FVTool lets you view the characteristics of
a designed or imported filter, including its
magnitude response, phase response, group
delay, pole-zero plot, impulse response, and
step response.
SPTool provides access to signal, filter, and
spectral analysis functions. You can:
• Measure and analyze the time-domain
information of one or more signals and
send audio signal to the PC’s sound card
• Apply the filter to a selected signal
• Graphically analyze frequency-domain
data using a variety of spectral estimation
methods, including Burg, FFT, multitaper
(MTM), MUSIC, eigenvector, Welch, and
Yule-Walker AR
Magnitude response of the specified
digital filter, created using FVTool.
Data markers determine the fre-
quency and magnitude values of
any chosen data point.
FDATool includes a Pole/Zero Editor that lets you design a filter
through the graphical placement of poles and zeros.
