    Abstract

    This paper presents an approach for the development of a number theoretic
    discrete Hilbert transform. The forward transformation has been applied by
    taking the odd reciprocals that occur in the DHT matrix with respect to a power
    of 2. Specifically, the expression for a 16-point transform is provided and
    results of a few representative signals are provided. The inverse transform is
    the inverse of the forward 16-point matrix.

    Abstract

    This paper presents a new discrete Hilbert transform (DHT) based measure of
    randomness for discrete sequences. The measure has been used to test three
    different classes of sequences with satisfactory results.
