Abstract
Improvements introduced in the object of the main Patent No. 257,703, issued May 6, 1960, by "Synchronous demodulator device", equipped with two amplifying elements each of which has at least one control electrode, called hereinabove. grid, and two other input and output electrodes, here called the anode and the cathode, in the preferred case in which said elements are triodes, the anode of the first element being coupled to the cathode of the second element, and being applied to said anode the carrier wave signal modulated by the signal that must be derived, through a capacitor, and a reference signal of carrier frequency is applied to the grid of each of said elements, being possible to derive the demodulated signal of the anode in a manner described in the main patent, the improvements being characterized in that the grids of said two elements receive the reference signal through windings that with They constitute the secondary windings of a transformer and each of which is connected between the grid and the corresponding cathode of an element.
