mapping:prep sampling fft
Version: 0.0.0
Description
Prepare time sampling optimum for FFT computation and expected frequencies in output.
Inputs
| Input | Name | Expected type(s) | Description |
|---|---|---|---|
| Pin 0 Required | time_freq_support | time_freq_support | Initial time domain TimeFreqSupport. |
| Pin 1 | cutoff_frequency | double | Cutoff 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 2 | number_sampling_point | int32 | For number of sampling point (calculation with cutoff_frequency is ignored). |
Outputs
| Output | Name | Expected type(s) | Description |
|---|---|---|---|
| Pin 0 | time_tfs_sampled | time_freq_support | Optimum sampled time domain TimeFreqSupport. |
| Pin 1 | freq_tfs_fft | time_freq_support | Frequency domain TimeFreqSupport expected in output of FFT. |
Configurations
| Name | Expected type(s) | Default value | Description |
|---|---|---|---|
| mutex | bool | false | If this option is set to true, the shared memory is prevented from being simultaneously accessed by multiple threads. |
