resistance of 2 Ωis shown in Fig. 11.11-9(a). Calculate and plot the output voltage
under steady-state.
[Hint: A symmetric square wave of ±1 V amplitude and fHz frequency can be
approximated by the truncated series
SOLUTION
When the rectangular waveform is switched on to the filter circuit, the system undergoes
the usual transient response and settles down to a steady-state in the long run. We look
at only the steady-state output in this example.
The waveform shown in Fig. 11.11-9(b) can be resolved into two components –
the first component is a DC of 12 V (that is the cyclic average value of v
