continuous Fourier transformationsThis devision is the most interesting in our company. Theoretical computations, development of electronic circuits and realisation of prototyps are our activities. For that we can look at a wide spectrum of special literature.
continuous Fourier transformations

CEPSTRUM-Analyses (like FFT)
2-D-FFT - discrete 2-Dimensions-Fourier-Transformations and 2-D-CEPSTRUM-Transformatuion of real-data up to 32768 MiB (BluRay)
computation of digital FIR-Filters (coeffizients on request), active filters and passive filters
filtering of series and *.wav-data within time area
filtering of spectrums
development of fast assembler programs (TASM, MASM32)
development of analoge and digital discret circuits (Spice)
active und passive antennas, matching calculations

While the Fourier-Transformation is an known tool of the engineering science, the CEPSTRUM-Analyses has to be explained. One application is the finding of signal-echos, for example by multi-way-radiations [Kemerait, R.C. and Childers, Signal Detection and Extraction by CEPSTRUM-Techniques, IEEE Trans. Info. Theory, Vol. IT-18, No. 6, pp. 745-759]. We changed the method, to determine the lenght of impulses for use in RADAR-device.
