Get underlying FIR filter
Syntax
Description
Examples
Get the Underlying FIR Filter of the Differentiator
Create a dsp.Differentiator
System object with default properties.
DF = dsp.Differentiator;
Use getFilter
to get the underlying FIR filter, filter
, which implements the differentiator, DF
.
filter = getFilter(DF)
