13. An apparatus for simultaneously sampling multiple-channel signals, comprising:
a code division multiplexing (CDM) modulator configured to modulate multiple target input signals, to obtain a single target analog signal;
a Delta-Sigma (ΔΣ) modulator configured to perform ΔΣ modulation on the single target analog signal to obtain a target digital bit stream, wherein an adder of the CDM modulator is integrated with a first-order integrator of the ΔΣ modulator;
a CDM demodulator configured to demodulate the target digital bit stream to obtain a target demodulated bit stream; and
a data filter configured to filter the target demodulated bit stream to obtain multiple target output signals.
