make.signal: Test signal generation

Description

Generates various test signals for wavelet transforms.

Usage

make.signal(name, n=1024, snr=Inf)

Arguments

name

a character string denoting the type of test signal to create. Supported values are: "dirac", "kronecker", "heavisine", "bumps", "blocks", "doppler", "ramp",

n

an integer specifying the length out the output series. Default: 1024.

snr

a numeric value representing the approximate signal to noise ratio of the output. Default: Inf (no noise).

Value
