Single Set Coefficient
Appendix A - Example 2
9. Fs/Fs1 - Enter the Stop-band Cutoff Frequency: Enter 11050 (Hertz) as the stop-band
cutoff frequency.
10. Rs - Enter the Stop-band Attenuation: Enter 98.5 (dB) as the Stop band Attenuation.
Drop the negative sign when entering this parameter.
11. Select MatLab
TM
Workspace: CLICK on the workspace location control for immediate
mode of coefficients generation.
12. Generate the Coefficients: CLICK on Apply to start the immediate mode of coefficients
generation process and send the set of coefficients to the MatLab
TM
workspace. This also
starts the Amplitude/Phase Plot shown in Figure 5 below:
Figure 5 - Amplitude/Phase Plot – Immediate Mode Operation, Single
12.1. Frequency-Magnitude (Hz-dB) Characteristics Plot: Shows the frequency-mag-
nitude characteristics graph for the set of coefficients generated for the filter and
allows design decisions to be made for actual FIR filters designed from the set of
entered parameters.
12.2. Frequency-Phase (Hz-degrees) Characteristics Plot: Presents the frequency-
phase characteristics plot representation for the entered set of filter coefficients.
The graph shows the user the ideal frequency-phase representation.
