Abstract : Phase interference filters are bridge networks in which the outputs of the bridge arms are added to produce filter effects. Previous methods for synthesizing this filter permitted no variations in the magnitude characteristics. A new method for determining the values of components is derived from analysis of the transfer function. This method enables the characteristics to be varied by moving the poles of the transfer function in the S-plane. Initial rates of decay of 12 decibels per octave with all poles real are possible. The rate of decay is increased to 18 decibels per octave, but the poles become complex. The transfer function permits further studies of the effects of changing pole locations. Transients can be investigated with analogue computers. (Author)
