Abstract: A method derives a frequency of a pulse signal from a line frequency. The method includes measuring a period of a line frequency pulse signal having the line frequency using a measured frequency derived from an oscillator frequency. The method further includes determining if the period of the line frequency pulse signal is within a predetermined tolerance limit. The line frequency is used to derive the frequency of the pulse signal when the period is determined to be within the predetermined tolerance limit, and the oscillator frequency is used to derive the frequency of the pulse signal when the period is determined to be outside the predetermined tolerance limit.

Abstract: In order to obtain a simple construction of an electricity meter (1), the invention provides that the meter comprises a highly integrated input module (3a, 3b, 3c) in which an analog-digital converter (5a, 5b) and an output module (7a) are integrated. A multiplying means (21) can optionally be integrated. Such an input module (3a, 3b, 3c), in combination with conventional components, especially microprocessors, makes it possible to produce an electricity meter which comprises a simple construction and which is of a single-phase and multi-phase type (also for a plurality of consumers).

Abstract: An SC-integrator comprises an amplifier connected to a circuit network, which includes an integrating capacitor and a storage capacitor. The storage capacitor is connected via a first switch to the output of the amplifier and via a second switch directly to one side of a switching circuit capacitor, which is also connected by means of third and fourth switches to ground and the inverting input of the amplifier, respectively. The other side of the switching circuit capacitor is connected by means of a fifth switch to an input voltage Vin, via a sixth switch to ground, and by means of a seventh switch to a reference voltage Vref. The SC integrator uses a storage capacitor of relatively low capacitance value, since the storage capacitor is connected in parallel with the switching circuit capacitor when effecting a reversal of the voltage polarity across the integrating capacitor.

Abstract: A multi-beam antenna for receiving microwaves emanating from at least first and second satellites comprising: a reflector which has a cylindro-paraboloidal shape (2) arranged substantially in the vertical plane and capable of focusing the incident microwaves on a substantially horizontal focal straight line (D) constructed from the foci (F1 to F5) of the reflector, at least first and second linear networks (R1, R2) being distributed substantially horizontally in the focal plane of the reflector, in order to receive and process, according to first and second laws of amplitude and time-lag, the incident microwaves emanating from first and second directions corresponding to the first and second satellites.
