Abstract :
Pole-zero concepts, with the associated techniques of signal flow graphs and root locus plots, are introduced and used in the analysis and synthesis of integrated loudspeaker-amplifier systems in the lower-frequency region. The case of the infinite baffle system is treated in detail, and formulas are developed for general voltage and current feedback. This is then simplified into a design method using only RC elements, and the compensation of the high-efficiency woofer in an undersized enclosure illustrates the method.
