Moreover, it is easy to prove that the orthogonal sum Hπ=HsinHHcos holds. In fact, using Euler formulas sintx=eitx-e-itx2iandcostx=eitx+e-itx2 we obtain Hsin⊂Hπ and Hcos⊂Hπ as sets, and 〉f,g〈Hsin=1/π〈f,g〉Hπ for c, g∈Hsin (the same occurs for f, g∈...

However, when these individual signals are combined to form the composite Alt-BOC signal, this constancy is lost in the resultant phased sum of these components. Hence, the amplitude of an Alt-BOC modulated signal is not constant. This modulation is known as nonconstant envelope Alt-BOC ...
PURPOSE: To make a small-scale circuit cope flexibly with alterations of process specifications and improve the versatility by reading data out of plural storage means according to pointers and performing addition/subtraction operation and the sum of product operation, and writing results while ...
Rani and Mishra16 studied weighted aggregated sum product assessment (WASPAS) methodology based on their proposed score function and similarity measures to address the alternative-fuel technology selection problem within q-ROFS context. Ali17 pointed out the drawbacks of the existing q-rung orthopair ...
