Resample_1

resample
Function: resample time series.
Format:
1.y of the resample = (x, P, q)
by using a polyphase filter for resampling time series, y is the length of the sequence obtained for the length of the original sequence x p / q times, p and q are a positive integer. In this case, the use of default using FIR method lowpass filter design antialiasing.
2.y = resample (x, p, q, n)
using the low-pass filter chebyshevIIR time series resample length of the filter is proportional to n, n default value 10. The
3. Y of the resample = ( X, P, Q, n-, Beta)
Beta Kaiser window used is a low-pass filter parameter, a default value is 5. the
4.y of the resample = (X, P, Q, B)
B is the resampling process filter coefficient vector.
5. [y, b] = resample (x, p, q)
coefficient vector b is the output parameter used by the filter.
Description:
x-- time series
p, q-- positive integer that specifies the multiple of the length of the resampling.
n-- specified chebyshevIIR low-pass filter employed in order, to the length of the filter and the ratio of n columns.
Kaiser window when using a low pass filter beta-- design parameters, the default value is 5.
