Performs the inverse of the real Walsh Hadamard transform.

It is WHI{X}=WH{X}/n, where n is the signal length of X. This VI is similar to the Walsh Hadamard Inverse VI.

Note By default, reentrant execution is enabled in all Point By Point VIs.

Inputs/Outputs

  • cbool.png initialize —

    initialize, when TRUE, initializes the internal state of the VI.

  • cdbl.png x —

    x is an input data point.

  • ci32.png sample length —

    sample length is the length of each set of incoming data. The VI performs computation on each set of data. The default is 128.

    sample length must be greater than zero and a power of 2.

  • i1ddbl.png Walsh Hadamard Inverse {X} —

    Walsh Hadamard Inverse {X} returns the inverse Walsh Hadamard transform of the set of input data points specified by sample length.

    In the case of an error, the VI returns an empty array.

  • 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.
