- *     h = fir1(28, 6/24);
- *
- * The first argument is the "order" of the filter and is always one less than the desired length. - * The second argument is the normalized cutoff frequency. This is in the range 0 (DC) to 1.0 (Nyquist). - * A 6 kHz cutoff with a Nyquist frequency of 24 kHz lies at a normalized frequency of 6/24 = 0.25. - * The CMSIS FIR filter function requires the coefficients to be in time reversed order. - * 
- *     fliplr(h)
- *
- * The resulting filter coefficients and are shown below. - * Note that the filter is symmetric (a property of linear phase FIR filters) - * and the point of symmetry is sample 14. Thus the filter will have a delay of - * 14 samples for all frequencies. - * \par - * \image html FIRLPF_coeffs.gif - * \par - * The frequency response of the filter is shown next. - * The passband gain of the filter is 1.0 and it reaches 0.5 at the cutoff frequency 6 kHz. - * \par - * \image html FIRLPF_response.gif - * \par - * The input signal is shown below. - * The left hand side shows the signal in the time domain while the right hand side is a frequency domain representation. - * The two sine wave components can be clearly seen. - * \par - * \image html FIRLPF_input.gif - * \par - * The output of the filter is shown below.
