Design of Precise Analog Frequency Multiplies of Harmonic Signals in Even Number of Times

In this paper the mathematical models and corresponding functional diagrams of precise frequency multiplies of harmonic signals in even number of times. The mathematical models are represented in a form of integral-differential equations. Functional diagrams are built on the basis of differentiators, integrators, summers, multipliers, dividers and functional transformers. A sensitivity of multiplier functioning to changes of its parameters have been investigated.
