upsampling

Upsample a Given Seismogram

Minimum version: v2.6

Syntax

upsampling (1) (2) [3] [4]
# (1) string, file path of the seismogram file
# (2) integer, upsampling rate
# [3] string, window type, default: 'Hamming'
# [4] integer, window length, default: 0

Remarks

The seismogram must be stored in double column plain text file. The first column stores the time series, and the second column stores the acceleration amplitudes.

The time series must be equally spaced.

The window type can be one of the following:

• Hamming

• Hann

• Blackman

• BlackmanNuttall

• BlackmanHarris

• FlatTop

If the upsampling rate is denoted as $L$, the window length is $nL+1$. The parameter $n$ is controlled by the last parameter.
