The characteristics of the continuous logic （CL） and its applications are studied. The results show that the conventional architecture of systems

with A/D and D/A converters to link up the analogue parts with the digital parts

might be changed by using CL.Thereafter the direct ultra high speed "digital processing" of the analogue signals could be realized.The applications as spread or compression of the time axis of the analogue signals

the digital controlled analogue signal delay circuits

the real-time voting circuits for analogue signals

realization of arbitrary function S = F（X

the exchange this for that between time

space and amplitude axes etc

are discribed.The real ICs of Continuous Logic applying to the high-speed realtime Fourier transformation are introduced. The results of the primary experimental set comes up to 16 MHz sampling frequency

and 2μs transform period for 32 points

with simple circuits and potentiality in much higher speed.
