tf.raw_ops.RFFT  Real-valued fast Fourier transform.  View aliases  Compat aliases for migration 
See Migration guide for more details. tf.compat.v1.raw_ops.RFFT  
tf.raw_ops.RFFT(
    input,
    fft_length,
    Tcomplex=tf.dtypes.complex64,
    name=None
)
 Computes the 1-dimensional discrete Fourier transform of a real-valued signal over the inner-most dimension of input. Since the DFT of a real signal is Hermitian-symmetric, RFFT only returns the fft_length / 2 + 1 unique components of the FFT: the zero-frequency term, followed by the fft_length / 2 positive-frequency terms. Along the axis RFFT is computed on, if fft_length is smaller than the corresponding dimension of input, the dimension is cropped. If it is larger, the dimension is padded with zeros.
 


 Args
  input   A Tensor. Must be one of the following types: float32, float64. A float32 tensor.  
  fft_length   A Tensor of type int32. An int32 tensor of shape [1]. The FFT length.  
  Tcomplex   An optional tf.DType from: tf.complex64, tf.complex128. Defaults to tf.complex64.  
  name   A name for the operation (optional).   
 


 Returns   A Tensor of type Tcomplex.
