Abstract: In an analog signal compression method with digital compression and digital expansion of linear based or sine-based linear signals, a signal coordination point is determined in a bi-adaptive scaleable mV/step and a time/step structured plane. To accomplish this, the linear or sine-based input signal is digitized, the breaks of the digitized linear or sine-based signal are detected, and the time difference and the amplitude difference of two successive breaks of the linear or sine-based signal are determined. This permits time differences and amplitude differences of successive breaks to be value coded as a data word on the basis of adaptive scaleable time-per-step tables and voltage-per-step tables so that the time-per-step tables and the voltage-per-step tables are selected depending on the absolute value of the determined time difference and amplitude difference, thus producing compressed data. An associated expansion method for reconstructing the original analog signal is also disclosed.

Abstract: In a process for receiving a broadband electromagnetic signal, the receiving spectrum is divided into n partial spectrums (n>1), which are subjected to parallel further processing in n channels. The resulting n partial signals are then demodulated into the base band, digitized by n equal-type analog-to-digital converters, and spectrally transformed by a fast Fourier Transform. Interfering edge effects at the transition to the respectively adjacent channel are compensated by amplitude and phase correction of the n partial signals for compensating. Finally, the partial spectrums of the n partial signals are integrated to form a total spectrum in the frequency domain.
