ABSTRACT:
A high-speed demodulating method of burst data capable of performing demodulation process at high speed in a single hardware structure. An input signal digitally modulated is taken in into an input unit to be sampled and latched therein by a sampling clock from a controller, and a modulation signal from the input unit is taken in into either a first demodulator or a second demodulator for each one burst data depending on the timing of a first control signal or a second control signal output by the controller, respectively, and demodulated, and a first demodulation signal produced from the first demodulator or a second demodulation signal produced from the second demodulator is taken in into an output unit by a third control signal output by the controller, and in the output unit, the first demodulation signal or the second demodulation signal is latched by a latch signal of the controller and supplied as an output signal.
