<h2>Przegląd</h2>
10+
11+
<p>This file describes how to create and edit time domain sample filters using
12+
Edit time domain sample filter dialog.</p>
13+
14+
<h2>Specifying filter parameters</h2>
15+
16+
<p>To create or edit a filter, you need to specify the following parameters:</p>
17+
18+
<ul>
19+
<li><b>Filter type</b> - describes what type of filter you want to design.<br/>
20+
Possible values:
21+
<ul>
22+
<li>low-pass</li>
23+
<li>high-pass</li>
24+
<li>band-pass</li>
25+
<li>band-stop</li>
26+
</ul>
27+
<li><b>Filter family</b> - is the type of approximation
28+
function which will be used to design this filter.<br/>
29+
Possible values:
30+
<ul>
31+
<li>Butterworth</li>
32+
<li>Chebyshev I</li>
33+
<li>Chebyshev II</li>
34+
<li>Elliptic</li>
35+
</ul>
36+
<li><b>Passband edge frequency 1</b> - is the passband boundary frequency
37+
which separates the passband from the transition band.
38+
<li><b>Passband edge frequency 2</b> - if the filter is a bandpass or a bandstop
39+
filter, then there are two transition bands. In that case passband edge
40+
frequency 1 separates the passband from the first transition band (and
41+
its frequency is lower), and the second passband edge frequency separates
42+
the passband from the second transition band.
43+
<li><b>Stopband edge frequency 1</b> - is the edge frequency which is the
44+
boundary between the stopband and the transition band in the filter's
45+
frequency response.
46+
<li><b>Stopband edge frequency 2</b> - if the filter is bandpass or bandstop,
47+
then there are two transition bands. In that case stopband edge frequency 1
48+
separates the stopband from the first transition band (and its frequency is
49+
lower), and the second passband edge frequency separates the passband from the
50+
second transition band.
51+
<li><b>Passband ripple</b> - is the maximum frequency response fluctuations
52+
which is allowed in the passband. For all frequencies in the passband, their
53+
attenuation must be less or equal than the value set by this control.
54+
<li><b>Stopband attenuation</b> - the minimum attenuation in the stopband.
55+
For all frequencies in the stopband, their frequency response magnitude must be
56+
attenuated at least by the value set by this control.
57+
</ul>
58+
59+
<p>The image below presents a frequency response of a Chebyshev I high-pass filter.
60+
The filter was designed using the following parameters:
61+
62+
<ul>
63+
<li><b>Filter type</b> = high-pass</li>
64+
<li><b>Filter family</b> = Chebyshev I</li>
65+
<li><b>Passband edge frequency 1</b> = 20 Hz</li>
66+
<li><b>Stopband edge frequency 1</b> = 16 Hz</li>
67+
<li><b>Passband ripple</b> = 3 dB</li>
68+
<li><b>Stopband attenuation</b> = 40 dB</li>
69+
</ul>
70+
71+
<p>Please note that the frequency response shown fulfills the requirements given.
72+
For example - the stopband ends at 16 Hz and all frequencies in the stopband are
73+
attenuated by at least 40 dB. The passband begins at 20 Hz and all frequencies in
74+
the passband are attenuated - at most - by 3 dB.</p>
75+
76+
<img src="images/highpassFilterFrequencyResponse.png" alt="High-pass Chebyshev I
77+
filter, passband edge frequency 1 = 16 Hz, stopband edge frequency 1 = 20 Hz,
78+
passband ripple = 3 dB, stopband attenuation = 40dB"/>
79+
80+
<p>An analogous frequency response graph for a band-stop filter would have two
81+
passbands (first: from 0 Hz to passband edge frequency 1, second: begins at passband
82+
edge frequency 2), one stopband (from stopband edge frequency 1 to stopband edge
83+
frequency 2), and two transition bands. A frequency response graph for a band-pass
84+
filter will have two stopbands, one passband, and two transition bands</p>
85+
86+
<p><b>Important - the maximum frequency that can be set using the frequency
87+
controls is the Nyquist frequency which is equal to the half of the
88+
signal's sampling frequency.</b></p>
89+
90+
<h2>Drawing filter frequency response</h2>
91+
92+
<p>A filter frequency response is a graph showing the filter's output spectrum,
93+
that is - how much is each frequency's magnitude attenuated in the signal
94+
which passes through the filter</p>
95+
96+
<p>To draw the frequency response of the filter designed using the controls
97+
in the Filter parameters panel, press the "Draw filter frequency response"
98+
button.</p>
99+
100+
<p>If the filter parameters are correct, the filter frequency response is drawn.
101+
Otherwise, a dialog containing error message is shown.</p>
102+
103+
<h2>Error messages</h2>
104+
105+
<p>The most common error message says that the designed filter order is too big.
106+
This happens, when the filter parameters are too strict. The more strict the
107+
parameters are, the harder for the designer is to design a filter fulfilling
108+
the specification given. For example - it is very hard for the designer to
109+
design a filter having very narrow transition bands (a transition band is
110+
narrow when a passband edge frequency is very close to the corresponding
111+
stopband edge frequency), a very small value of ripple in the passband and
112+
having all of the frequencies in the stopband strongly attenuated.</p>
113+
114+
<p>If such an error shows up, please make the parameters less strict.</p>
115+
116+
<p>Another solution for that error is changing the Filter family of the filter.
117+
Filters approximated using the Chebyshev approximation functions tend to have
118+
smaller filter order comparing
119+
to Buttorworth filters having similar filter parameters. What's more, filters
120+
approximated using the Elliptic functions have smaller filter order
121+
comparing to a Chebyshev filter having similar parameters.</p>
