The TD_CONVOLVE takes input sources each containing either univariate or multivariate series instances. The first series referenced in the function call is referred to as the primary series, and the second series referenced is the secondary series. The first input contains the series that is to be filtered by the convolve operation. The second input contains the filter series to be applied to the first input. The result series inherits the SERIES_ID() identifiers from the primary series.
The two source inputs have the following characteristics.
- PAYLOAD CONTENT must have one of these values:
- REAL
- COMPLEX
- MULTIVAR_REAL
- MULTIVAR_COMPLEX
- The two input sources must have the same CONTENT value and number of PAYLOAD fields, with these exceptions:
- One of the two inputs can have CONTENT value MULTIVAR_REAL and multiple PAYLOAD fields and the other input can have CONTENT value REAL and one PAYLOAD field.
- When both inputs have the CONTENT value MULTIVAR_COMPLEX, one input can have multiple pairs of PAYLOAD fields and the other input can have a single pair of PAYLOAD fields.
