Relationships among digital one/half band filters, low/high order differentiators and discrete/differentiating Hilbert transformers

It is shown that there exists a close relationship among digital one/half band filters, low/high order differentiators, and discrete/differentiating Hilbert transformers. An attempt is made to present a complete picture of their interrelationships and conversions between one another. A table and some block diagrams have been developed for their impulse response connections, and a design example is also given for illustration
