decimate

class diffsptk.Decimation(period, start=0, dim=-1)

See this page for details.

Parameters:

periodint >= 1

Decimation period, \(P\).

startint >= 0

Start point, \(S\).

dimint

Dimension along which to shift the tensors.

forward(x)

Decimate signal.

Parameters:

xTensor [shape=(…, T, …)]

Signal.

Returns:

outTensor [shape=(…, T/P-S, …)]

Decimated signal.

Examples

>>> x = diffsptk.ramp(9)
>>> decimate = diffsptk.Decimation(3, start=1)
>>> y = decimate(x)
>>> y
tensor([1., 4., 7.])
