    tf.signal.fft(
        input: Annotated[Any, TV_FFT_Tcomplex], name=None
    ) -> Annotated[Any, TV_FFT_Tcomplex]

Computes the 1-dimensional discrete Fourier transform over the inner-most
dimension of `input`.

| ## Args ||
|---|---|
| `input` | A `Tensor`. Must be one of the following types: `complex64`, `complex128`. A complex tensor. |
| `name` | A name for the operation (optional). |

<br />

<br />

<br />

| ## Returns ||
|---|---|
| A `Tensor`. Has the same type as `input`. ||
