fvtool
Description
Examples
View octaveFilterBank
in FVTool
Create an octaveFilterBank
object. Call fvtool
to visualize the filter bank.
octFiltBank = octaveFilterBank; fvtool(octFiltBank)
ans = Figure (filtervisualizationtool) with properties: Number: [] Name: 'Figure 1: Magnitude Response (dB)' Color: [0.9400 0.9400 0.9400] Position: [348 376 583 437] Units: 'pixels' Use get to show all properties
To visualize a subset of filters in the filter bank, specify the second argument as a row vector of indices between one and the number of filters in the filter bank. If not specified, fvtool
visualizes 1 to N filters of the filter bank, where N is the smallest of octFiltBank.NumFilters
and 64
. Visualize the ninth filter.
fvtool(octFiltBank,9)
ans = Figure (filtervisualizationtool) with properties: Number: [] Name: 'Figure 2: Magnitude Response (dB)' Color: [0.9400 0.9400 0.9400] Position: [348 376 583 437] Units: 'pixels' Use get to show all properties
To specify the number of points in the frequency response, use the N
name-value argument. Specify that the frequency response contains 8192 points.
fvtool(octFiltBank,N=8192)
ans = Figure (filtervisualizationtool) with properties: Number: [] Name: 'Figure 3: Magnitude Response (dB)' Color: [0.9400 0.9400 0.9400] Position: [348 376 583 437] Units: 'pixels' Use get to show all properties
View gammatoneFilterBank
in FVTool
Create a gammatoneFilterBank
object. Call fvtool
to visualize the filter bank.
gammaFiltBank = gammatoneFilterBank; fvtool(gammaFiltBank);
To visualize a subset of filters in the filter bank, specify the second argument as a row vector of indices between one and the number of filters in the filter bank. If not specified, fvtool
visualizes 1 to N filters of the filter bank, where N is the smallest of gammaFiltBank.NumFilters
and 64
. Visualize the ninth filter.
fvtool(gammaFiltBank,9);
To specify the number of points in the frequency response, use the N
name-value argument. Specify that the frequency response contains 8192 points.
fvtool(gammaFiltBank,N=8192);
Input Arguments
