In this example, the signal is two-dimensional (2D).
Input
- InputTable: fft_output2, output by FFT Example: 2D Signal
SQL Call
CREATE MULTISET TABLE ifft_output_table2 AS ( SELECT * FROM IFFT ( ON fft_output2 AS InputTable PARTITION BY id_0 ORDER BY timestep USING TargetColumns ('real_value1', 'imag_value1') Dimensions (2) RealValuedSignal ('false') ) AS dt ) WITH DATA;
Output
This query returns the following table:
SELECT * FROM ifft_output_table2;
id_0 timestep real_real_value1 imag_real_value1 ---- -------- ---------------- ---------------- 1 3 3.0 0.0 1 4 4.0 0.0 1 2 2.0 0.0 1 1 1.0 0.0
