  This paper investigates the problem of sampling and reconstructing bandpass
signals using time encoding machine(TEM). It is shown that the sampling in
principle is equivalent to periodic non-uniform sampling (PNS). Then the TEM
parameters can be set according to the signal bandwidth and amplitude instead
of upper-edge frequency and amplitude as in the case of bandlimited/lowpass
signals. For a bandpass signal of a single information band, it can be
perfectly reconstructed if the TEM parameters are such that the difference
between any consecutive values of the time sequence in each channel is bounded
by the inverse of the signal bandwidth. A reconstruction method incorporating
the interpolation functions of PNS is proposed. Numerical experiments validate
the feasibility and effectiveness of the proposed TEM scheme.
