A live webcast titled "Filter Design for PWM Systems, Digital Audio vs. Switching Supplies" will be presented by Texas Instruments and Avnet Electronics Marketing on Wednesday, October 10, 2007, at 11:00 a.m. CDT (18:00 hrs CET). The webcast will highlight how the function of an L-C filter is modified when used with a power converter or a Class-D amplifier.
During the webcast, TI analog expert Bill Klein and panelists Fred Shipley of TI and Val Rhodes of Avnet will discuss how to maximize performance of the L-C filter in various designs. During the lab session, the panelists will highlight the key parameters in the L-C filter design for the two applications and offer a simplified approach to the L-C filter design for the Class-D amplifier.
Through simulation and a lab experiment, the panelists will illustrate the effect of correct and incorrect inductor selection in the output filter of a Class-D amplifier. Registration for the free one-hour session is available at www.ti.com/elabwebcast.
