Abstract: 1,206,161. Power spectrum analysers; cross-power analysers. SOLARTRON ELECTRONIC GROUP Ltd. Jan.12, 1968 [Jan.17, 1967], No.2489/67. Heading G1U. In a power spectrum analyser a signal x (t) is multiplied by local oscillations sin wt and cos wt (in phase quadrature) in multiplicative mixers 10, 11, the outputs being passed through low-pass filters 13, 14 to an adder circuit 18, squarer 21 and averaging circuit 19, one of the filters being connected to the adder 18 through a reversing switch 20. This switch switches the filter 14 output between positive and negative values thereof and its operating frequency is higher than the cut off frequency of the filters 13, 14, so that any product forms a (t) b(t) at the output of the squarer 21 are reduced to negligible proportions and the squarer output represents the power of x(t) at the frequency of the multiplying sine and cosine signals. The squarer and averager may comprise a thermocouple having its output connected to an RMS meter. In a cross-power spectrum analyser Fig.4 (not shown) for measuring the in-phase and quadrative power between two signals x(t), y(t), the Fig.2 circuit as far as the adder 18 is duplicated, x(t), being fed to two of the multipliers and y(t) to the other two, the outputs of the adder circuits being fed through a further multiplier (25) to an averaging circuit. For measuring in-phase cross-power the reversal switches are connected in series with those multipliers fed with in-phase multiplying signals and for measuring quadrature cross-power one of the reversal switches is connected in series with the other multiplier feeding its respective adder circuit. In a modification of the Fig. 2  circuit, the reversal switch 20 and adder 18 are replaced by a changeover switch 35, Fig.6 (not shown) which alternately connects the output of the filters 13, 14 to the squarer 21. Similar modifications may be made to the circuit of the cross-power analyser.

Filed: 1947-01-28
Abstract: 665,875. Velocity modulated apparatus. ENGLISH ELECTRIC VALVE CO.. Ltd. Nov. 7, 1947 [Jan. 28, 1947], No. 2674/47. Class 39 (i). [Also in Group XL(c)] High-frequency oscillatory apparatus comprises at least one length of wave-guide having a thin substantially planar resonant window formed by a narrow gap between two conductive members, projecting from the walls of the guide, across which is a voltage antinode. and an electron stream is projected across said gap so that it is velocity-modulated and reflected to recross the gap and deliver energy thereto; or it may cross a second narrowgapped resonant window. The dumb-bellshaped window 2a, 2b (Fig. 1), is one arrangement, an electron stream being projected across the slit 2b to the reflector electrodes. In Fig. 3. partitions 2c, 2d and hollow cylindrical members 3, 4 form the resonant window, the members 3, 4 containing the cathode 6, focusing electrode grids 9, 10 and reflector anode 8, respectively, alternatively, a pair of screws or bolts may replace partitions 2c, 2d and the reflector electrode 8 may be replaced to allow the modulated stream to pass across a resonant window in a parallel wave-guide, the two waveguides having a common wall. The electron stream may be flat or ribbon-shaped. Feedback from wave-guide to wave-guide is across an apertured partition. Frequency of operation is altered by changing the dimensions of the resonant window without changing the gap; an adjustable screw may tune the wave-guide. In operation one end of the wave-guide is n# loaded and the other closed at a distance of - 4 from the resonant window. n being an odd number. Feeding energy at one frequency into the apparatus operating at a different frequency gives a heterodyne action and a changed frequency output. Modulating the potential or the reflector electrode yields frequencymodulated signals.
