How do we make sense of this? First, we note that R2 and C3 form a first order low pass filter and L3 and C4 form another low pass filter. Both low
pass filters have been set at the same cutoff frequency. The combination of both form a two stage filter to remove the high frequency content
present in the DAB signal. Capacitor C5 is used to remove any residual DC offset in the signal.
But let's just deal with the AC steady state response, which means that you don't need to know any of these details, and then can conveniently treat
this circuit as a blackbox.
What is the theoretical cutoff frequency for the RC and LC filters shown in Figure 9? Answer to within 1% accuracy.
