Method and system for controlling and stabilising the frequency of a signal generated by a controllable oscillator

摘要: A method and a system are described for controlling stabilizing in time, as temperature changes, the frequency of signal generated by controllable oscillator (3), said comprising steps of: - measuring (3) using first signal, whose duration is proportional to length delay line (5) at least (7) second (9) portions arranged series having (L1) (L2) lengths, respectively; applying correction if difference between desired value exceeds predetermined threshold; providing portion coupling conductive material dielectric negative gradient its constant function temperature; or another temperature, absolute being greater than that gradient; selecting manner such relation L 2 = (L 1 ⋅ ΔR ) / abs (ΔR true, wherein represent, respectively, variations introduced portions, variation smaller, each Kelvin degree, thermal expansion coefficient material.
