qmf R Documentation
Quadrature Mirror Filter
Description
Computes the quadrature mirror filter from a given filter.
Usage
qmf(g, low2high = TRUE)
Arguments
g
Filter coefficients.
low2high
Logical, default is TRUE which means a low-pass
filter is input and a high-pass filter is output. Setting low2high=F
performs the inverse.
Details
None.
Value
Quadrature mirror filter.
