Inputs/Outputs

  • c1ddbl.png X —

    X is an array of power of 2 length.

  • i1ddbl.png Walsh Hadamard Inverse {X} —

    Walsh Hadamard Inverse {X} returns the inverse Walsh Hadamard transform of X.

  • ii32.png error —

    error returns any error or warning from the VI. You can wire error to the Error Cluster From Error Code VI to convert the error code or warning into an error cluster.

    • If WH{X} denotes the Walsh Hadamard transform of X and WHI{X} denotes the inverse Walsh Hadamard transform, then it is

    WHI{WH{X}} = WH{WHI{X}} = X.

    Furthermore, the following equation is valid

    ,

    where n is the length of the signal X.
