}
BartlettHann is a BartlettHann window maker. For more info, see https://en.wikipedia.org/wiki/Window_function#Bartlett-Hann_window
func NewBartlettHann ¶
func NewBartlettHann() *BartlettHann
NewBartlettHann makes a new BartlettHann window maker.
func (*BartlettHann) Make ¶
func (w *BartlettHann) Make(size int) []float64
Make BartlettHann window of a given size (number of samples).
type Blackman ¶
type Blackman struct {
}
Blackman is a Blackman window maker. For more info, see https://en.wikipedia.org/wiki/Window_function#Blackman_window
type BlackmanHarris ¶
type BlackmanHarris struct {
}
BlackmanHarris is a BlackmanHarris window maker. For more info, see https://en.wikipedia.org/wiki/Window_function#Blackman-Harris_window
func NewBlackmanHarris ¶
func NewBlackmanHarris() *BlackmanHarris
NewBlackmanHarris makes a new BlackmanHarris window maker.
func (*BlackmanHarris) Make ¶
func (w *BlackmanHarris) Make(size int) []float64
Make BlackmanHarris window of a given size (number of samples).
type BlackmanNuttall ¶
type BlackmanNuttall struct {
}
BlackmanNuttall is a BlackmanNuttall window maker. For more info, see https://en.wikipedia.org/wiki/Window_function#Blackman-Nuttall_window
func NewBlackmanNuttall ¶
func NewBlackmanNuttall() *BlackmanNuttall
NewBlackmanNuttall makes a new BlackmanNuttall window maker.
func (*BlackmanNuttall) Make ¶
func (w *BlackmanNuttall) Make(size int) []float64
Make BlackmanNuttall window of a given size (number of samples).
type Cosine ¶
type Cosine struct {
}
Cosine is a Cosine window maker. For more info, see https://en.wikipedia.org/wiki/Window_function#Cosine_window
type FlatTop ¶
type FlatTop struct {
}
FlatTop is a FlatTop window maker. A flat top window is a partially negative-valued window that has a flat top in the frequency domain. They are designed to have a broader bandwidth and so have a poorer frequency resolution, leading to low amplitude measurement error suitable for use in in spectrum analyzers for the measurement of amplitudes of sinusoidal frequency components For more info, see https://en.wikipedia.org/wiki/Window_function//Flat_top_window
type Gaussian ¶
type Gaussian struct {
// contains filtered or unexported fields
}
Gaussian is a Gaussian window maker. For more info, see https://en.wikipedia.org/wiki/Window_function#Gaussian_windows
func NewGaussian ¶
NewGaussian makes a new Gaussian window maker. Sigma must be <= 0.5.
type Hamming ¶
type Hamming struct {
}
Hamming is a Hamming window maker. For more info, see https://en.wikipedia.org/wiki/Window_function#Hann_and_Hamming_windows
type Hann ¶
type Hann struct {
}
Hann is a Hann window maker. For more info, see https://en.wikipedia.org/wiki/Window_function#Hann_and_Hamming_windows
type Lanczos ¶
type Lanczos struct {
}
Lanczos is a Lanczos window maker. The Lanczos window is used in Lanczos resampling. For more info, see https://en.wikipedia.org/wiki/Window_function#Lanczos_window.
type Nuttall ¶
type Nuttall struct {
}
Nuttall is a Nuttall window maker. For more info, see https://en.wikipedia.org/wiki/Window_function#Nuttall_window.2C_continuous_first_derivative.
type Rectangular ¶
type Rectangular struct {
}
Rectangular is a Rectangular window maker. Produces a rectangular window (all ones) of a given size (number of samples). For more info, see https://en.wikipedia.org/wiki/Window_function#Rectangular_window.
func NewRectangular ¶
func NewRectangular() *Rectangular
NewRectangular makes a new Rectangular window maker.
func (*Rectangular) Make ¶
func (w *Rectangular) Make(size int) []float64
Make Rectangular window of a given size (number of samples).
type Triangular ¶
type Triangular struct {
}
Triangular is a Triangular window maker. Endpoints are near zero. Midpoint is one. There is a linear slope between endpoints and midpoint. For more info, see https://en.wikipedia.org/wiki/Window_function//Triangular_window
func NewTriangular ¶
func NewTriangular() *Triangular
NewTriangular makes a new Triangular window maker.
func (*Triangular) Make ¶
func (w *Triangular) Make(size int) []float64
Make Triangular window of a given size (number of samples).
type Tukey ¶
type Tukey struct {
// contains filtered or unexported fields
}
Tukey is a Tukey window maker. The Tukey window, also known as tapered cosine, can be regarded as a cosine lobe of width alpha * N / 2 that is convolved with a rectangular window. At alpha = 0 it becomes rectangular, and at alpha = 1 it becomes a Hann window. For more info, see https://en.wikipedia.org/wiki/Window_function//Tukey_window.
type WindowMaker ¶
Window makes windows of a certain kind.
