Supports all 4
cases of FIR linear phase design. (Symmetrical/Asymmetrical; Odd/Even Filter
Length).
Has the built-in
AI to determine the particular case of FIR filter to be designed based on the
specified filter length.
Handles various
types of filter responses. (LPF, HPF, BPF, BSF, Differentiator Filter, Hilbert
Transformer Filter & Multi-Band Filter).
Able to design
window functions filters or equiripple filters. (Rectangular, Hanning,
Hamming, Blackmann, Kaiser, Weighted Least Squares method for equiripple
design).
Encompasses
options for saving and loading of our filter design to files for further uses.
Incorporates
printing functions for the filter coefficients values and graphical response
plots.
User is able to
select the type of graphical plots for display (Impulse Response, Magnitude
Response, Logarithmic Magnitude Response & Phase Response)
Contains option to
combine the logarithmic plots of two different/same type of filters together
for comparison.
Zooming in
function in the form of pass-band view, stop band view & frequency range
specifications lets the user zoom in to any portion of the graphical for a
more detailed analysis.
Display of filter
coefficients on screen provides an easier avenue for filter design
verification.
.
Has the option for
auto filter length calculation for window functions filters based on specified
transition width or designing filter length specified filter.
User is able to
view all the plots associated with FIR filters (Impulse Response, Magnitude
Response & Phase Response).
In the equiripple
design, user is able to specify the individual band frequencies and
amplitudes.
Incorporates an
unlimited iterations for the design of equiripple filter.
User can also
selects to terminate the iterative algorithm for the equiripple filter design
based on the ratio of peak ripple error between two consecutive iterations.
