Real-time spectrum analysis of electrical signals and image transformation techniques and device for real-time signal processing in accordance with a hierarchical pyramid

摘要

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.
