Syntax

visualize(shelvFilt)
visualize(shelvFilt,NFFT)
hvsz = visualize(___)

Description

visualize(shelvFilt) plots the magnitude response of the shelving filter. The plot is updated automatically when you change the object properties.

example

visualize(shelvFilt,NFFT) specifies an N-point FFT to calculate the magnitude response.

hvsz = visualize(___) returns a handle to the visualizer as a dsp.DynamicFilterVisualizer object when you call this syntax with any of the previous input arguments.

Examples

Open Live Script

Create a shelvingFilter object, and then call visualize to plot the magnitude response of the filter.

shelvFilt = shelvingFilter(2,1,400,"lowpass");
visualize(shelvFilt)

Modify the gain and observe that the plot is updated automatically.

shelvFilt.Gain = 10;

Input Arguments

collapse all

Shelving filter whose magnitude response you want to plot, specified as a shelvingFilter System object™.

Number of bins used to calculate the DFT, specified as a positive scalar.

Data Types: single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64
