Abstract
ABSTRACTThe Weaver technique or the third method of generation of single sideband modulation with suppressed carrier (SSB-SC) amplitude modulation (AM) signals is one such algorithm which looks deceptively simple when compared with the more analytically tractable phase-shift method. With the advent of digital signal processing (DSP) techniques such as the CORDIC (coordinate rotation digital computer) algorithm, an elegant low-complex implementation of the Weaver technique is now feasible, which necessitates a better understanding of the underlying principle. However, despite its popularity, it is not explained in detail in conventional text books on communication engineering and in general literature. Using the background theory of complex signals (I and Q), in this paper, we have depicted the entire operation graphically. Combined with necessary mathematics and implementation ideas, this will be a comprehensive tutorial on the third method of SSB-SC generation and should motivate students to look at the underlying mathematical theory of problems in the area of communications and signal processing for similar interpretations.
