Abstract :
In this article I present the components of a circuit that is designed to improve the signal/noise communications using frequency modulation. Circuit was made interposing between two active filters, Sallen-Key second order, a non-inverting amplifier. The proposed scheme was analyzed with the program Macker circuit and voltage dependence graph/time has been translated in coordinates voltage/frequency to emphasize the function performed by the circuit.
