Description

Creates artificial test signal identical to the standard test signals proposed and used by D. Donoho and I. Johnstone in WaveLab (a MATLAB toolbox developed by Donoho et al. the statistics department at Stanford University).

Usage

makesig(sigName, N)

Arguments

sigName Name of desired signal. Valid values are:
SIGNAL.ALL
SIGNAL.HEAVI.SINE
SIGNAL.BUMPS
SIGNAL.BLOCKS
SIGNAL.DOPPLER
SIGNAL.RAMP
SIGNAL.CUSP
SIGNAL.SING
SIGNAL.HI.SINE
SIGNAL.LO.SINE
SIGNAL.LIN.CHIRP
SIGNAL.TWO.CHIRP
SIGNAL.QUAD.CHIRP
SIGNAL.MISH.MASH
SIGNAL.WERNER.SORROWS (Heisenburg)
SIGNAL.LEOPOLD (Kronecker)
N Length in samples of desired signal (512 by default)

Value

Returns a list with components:

x vector (or matrix) of test signals
N length of signal returned

Note

Using the value SIGNAL.ALL.SIG for sigName returns a matrix containing the vectors of all the other signals.
