Abstract: An apparatus and method for use by a receiver in decoding information sent by phase-shift keying over a carrier frequency is disclosed. The method is well suited for use with power line carrier (PLC) applications as it is adapted to appropriately position the sampling window based on a zero crossing of one of the phases of the power line. The method allows for receipt and processing of information on more than one carrier frequency and from transmitters operating on a phase of the power line that is different than the phase used by the receiver to detect the zero crossings of the alternating current at the power grid frequency on the power line. A number of alternative embodiments are included.

Abstract: This invention provides a method for designing a waveguide profile based upon predicted performance measurements of the waveguide. The method involves establishing a design metric, such as the change in acoustic reactance along the transition of the waveguide. Initial values may then assigned for the radius or diameter of the throat of the waveguide as well as values for the initial slope of the waveguide along the major and minor (or x and y) axis and the depth of the waveguide. The waveguide may then be divided into two or more sections. The values of the slopes for each section are then altered based upon the design metric. When using the change of acoustic reactance as the design metric, the slope of each section of the waveguide is adjusted to minimize the change in acoustic reactance between the sections, which is the desired performance standard.
