mapping:prep sampling fft

Version: 0.0.0

Description​

Prepare time sampling optimum for FFT computation and expected frequencies in output.

Inputs​

InputNameExpected type(s)Description
Pin 0
Required
time_freq_supporttime_freq_supportInitial time domain TimeFreqSupport.
Pin 1cutoff_frequencydoubleCutoff Frequency. In this case, number of points is calculated computing (time_range * cutoff_freq * 2) and taking the next power of 2 (optimum for fft calculation).
Pin 2number_sampling_pointint32For number of sampling point (calculation with cutoff_frequency is ignored).

Outputs​

OutputNameExpected type(s)Description
Pin 0time_tfs_sampledtime_freq_supportOptimum sampled time domain TimeFreqSupport.
Pin 1freq_tfs_ffttime_freq_supportFrequency domain TimeFreqSupport expected in output of FFT.

Configurations​
