where
denotes Fourier transform operator,
for continuous inputs and It is seen that to obtain the
frequency domain response of the circuit, the Fourier transform of the
network variables at the end of each clock phase is needed. To obtain
the Fourier transform of we notice that the sub-circuit
associated with the clock phase is essentially a linear time-invariant
circuit with the initial conditions given by
To
analyze this circuit, we reset the time origin to
The
input of the circuit becomes
and the circuit is
depicted by
and for
Its response at the end of the clock phase
is obtained
from the sampled-data simulation with the time step
