/** @brief Signal resampling
|
|
*
|
|
* @param[in] inputSignal Array with input signal.
|
|
* @param[out] outSignal Array with output signal
|
|
* @param[in] inFreq Input signal frequency.
|
|
* @param[in] outFreq Output signal frequency.
|
|
* Signal resampling implemented a cubic interpolation function and a filtering function based on Kaiser window and Bessel function, used to construct a FIR filter.
|
|
* Result is similar to `scipy.signal.resample`.
