Abstract:
A method of frequency multiplication, the method comprising:providing a plurality of circuit modules for realizing Chebyshev polynomials of the nth order T.sub.n (x)), the Chebyshev polynomials having arithmetic properties and being defined by T.sub.n (cos(.omega.t))=cos(n.omega.t);interconnecting the circuit modules to form a modular circuit array or a modular circuit structure using at least one of the relations T.sub.nm (x)=T.sub.n (T.sub.m (x)) and T.sub.n+m (x)=T.sub.n (x)T.sub.m (x)-T.sub.n-m (x); andapplying to an input of the circuit module for the Chebyshev polynomial (T.sub.n (x)) a cosinusoidal oscillation having a first frequency so as to generate a cosinusoidal oscillation having a second frequency at an output of the circuit module, the second frequency being a factor of n times the first frequency.
