The article deals with the researching the compensation devices to measure the altitude of altitude-modulated signals and it derivatives. The synchronous detection in these devices is combined with calculating of derivatives. It analyzed by the method of polyharmonical linearization. It shown, that the devices can be searched in form of double system of equations – one for altitude and it derivatives, another – for high harmonics of modulation.
