Analog synthesizer of orthogonal signals

A new adaptive architecture, an analog synthesizer of orthogonal signals wh ich is able to produce a plurality of mutually orthogonal signals as functi ons of time, such as Legendre polynomials, cosine basis of functions, smoot hed-cosine basis, etc., is proposed and analyzed, A method for the creation of analog devices with Chebyshev polynomials and Legendre polynomial trans fer functions is proposed, A proof of-concept breadboard version of the ana log synthesizer is described. The results of smoothed-cosine basis synthesi s, as well as characteristics of output functions, are then presented. The device is characterized by a very fast and stable process of signals synthe sis.
