Output low-pass filter
To avoid EMI problems, it may be necessary to use a low-pass filter before the speaker. The
cutoff frequency should be larger than 22 kHz and much lower than the output switching
frequency. It is necessary to choose the L-C component values depending on the loud
speaker impedance. Some typical values, which give a cut-off frequency of 27 kHz, are
shown in
