METHOD FOR SPECTRAL-TEMPORAL SIGNALS TRANSFORMATION Russian patent published in 2005 - IPC

FIELD: radio engineering.

SUBSTANCE: signal U₁ is converted from analog form to frequency form, forming its frequency spectrum S₁, received frequency spectrum S₁ is converted to frequency spectrum S₂ by multiplication of each component of spectrum S₁ on transformation coefficient N - constant, value of which is selected on basis of providing of necessary length of output signal, frequency spectrum S₂ is scaled by division of amplitude of each component on compression coefficient N, thereby forming scaled frequency spectrum S_2m, scaled frequency spectrum S_2m is converted from frequency zone to time zone, thereby forming a digital signal, which is then converted from digital form to analog with parameters different from base signal.

EFFECT: simplified construction, broader functional capabilities, higher efficiency.
