speakers used in portable systems, whether internal or ex-
ternal, have little ability to reproduce signals below 150Hz.
Applications using speakers with this limited frequency re-
sponse reap little improvement by using high value input and
output capacitors.
As shown in Figure 1, the internal input resistor, R
input capacitors, C1 and C2, produce a -3dB high-pass filter
cutoff frequency that is found using Equation (2).
