Abstract: A pipeline structure (Figure 3) is used for one or both of the following processes: (a) for the analysing, occurring at delayed real time, of the frequency spectrum of an information component (having one or more dimensions) of a given time signal (G0), the maximum frequency of interest of which is no greater than f0 and (b) for synthesising, in delayed real time, such a temporal signal (G0) from its frequency analysis spectrum (L0...G OMEGA ). Such a pipeline structure is particularly suitable for image processing of the two-dimensional space frequencies of television images which are defined by a temporal video signal (Figure 3). … …

Abstract: Noise reduction is achieved, without the introduction of noticeable artifacts in the displayed image, using (1) a non-ringing, non-aliasing, localized transfer, octave-band spectrum analyzer for separating the video signal representing the image into subspectra signals, (2) separate coring means for one or more of the analyzed subspectra signals, and (3) then a synthesizer employing one or more non-ringing, non-aliasing filters for deriving an output image-representing signal from all of the subspectra signals.

Abstract: PURPOSE: To efficiently and accurately obtain a complex signal by inserting a delay and forming information samples, simultaneously generated in each adder when signals, having time deviation in a signal group is transmitted thereby composing the composite signal in real time. CONSTITUTION: 1st input terminals of relay means 100-2 to 100-n are connected to the 1st output terminals of relay means 100-1 to (n-1) respectively. Then, sampling frequency clocks CL1 to CLn are applied to other input terminals, and other input terminals are corrected by correcting parts 345 to 349, via delays 340 to 344 and connected to adders ADD 359 to 363, respectively. For example, when a thirdly generated signal and a fourthly generated signal are combined and transmitted, it causes time deviation. Then, the 3rd signal precedented generated is delayed for a prescribed time by the delay 342 to form an information sample practically simultaneously generated in the adder 359. Thus, since the composite signal is composed only by a realtime processing, a complex signal is obtained. efficiently and accurately.
