A unified approach—based on Padé Approximants—is presented for the design of simultaneous equal constraints non‐minimum phase distributed filters. The results obtained indicate that this method is more general than previous methods, and allow considerable freedom for the control of both amplitude and delay. The procedure outlined can apply for any transfer function with arbitrary characteristics.
