Abstract: A microwave filter is disclosed in which open-ended lines (14, 15, 16) are connected at three or four points of a main line (13) having input and output terminals (11, 12) the open-ended lines (14, 15, 16) having a length about one fourth the wavelength of an image signal frequency, to produce a band-stop filter characteristic at an image frequency; all or parts of the open-ended lines (14, 15, 16) constitute open-ended parallel-coupled lines arranged in parallel to the main line (13), and the intervals of connection of the open-ended lines (14, 15, 16) with the main line (13) are properly selected. The insertion loss of the filter within the pass band of a radio frequency signal is reduced and the filter attenuation within a stop band of an image signal is increased, thus providing a compact band-­stop filter which has a steep rise characteristic.

Abstract: A compensation circuit for very fast current fluctuations, as occur in a pair of leads (11.1, 11.2) of a load circuit (12), has an npn transistor (17), a base diode (18), a base resistor (19), a collector diode (20) and a collector resistor (21). A current of predetermined intensity flows through the current compensation circuit (10) when a normal current is flowing through the load circuit, i.e. a current without surges or interruptions. However, if a voltage interruption occurs, the current compensation circuit very quickly reduces its own current consumption, as a result of which more current is available for the load circuit. The very fast switching takes place in that the transistor is supplied with control current with the aid of the depletion layer capacitance of the base diode, and the transistor has a high transit frequency. In order that the circuit reacts as quickly as possible, it must be arranged as closely as possible to the load circuit. <IMAGE>

Abstract: 2.1 In order to avoid setting up a connection between devices, e.g. cordless telephones, which are not associated with one another in pairs, it is known for the devices which are associated with one another in pairs to exchange identifications with one another throughout the duration of the connection. Such an identification transmission can be noticed during speech reception by "interfering pips" which have an adverse effect on conversation. 2.2 In devices which are associated with one another in pairs, the exchange of identifications during the conversation can be carried out such that this is hardly detectable by the user and the circuitry complexity which is necessary for this purpose remains as low as possible, if the first device transmits a first part of the identification, the second device compares the received identification part with a first part of the common identification and the second device transmits a second part of its identification in the event of coincidence of said first part of the identification, and that the identification part received in the first device is compared with a second part of the common identification. 2.3 One field of application of the invention is in the area of cordless telephones. <IMAGE>

Abstract: A method and apparatus for diversity reception in a communication system is provided. A dual branch receiver (100, 101) is provided with a stored replica of expected reference information (104) so that correlation with received time-dispersed signals produces an estimate of the transmission channel's impulse response as seen by each branch (100, 101), and determines, among other things, phase error between the branch local oscillators (208, 209) and the time-­dispersed signals. Matched filters (214, 215) are constructed which then coherently align the time-dispersed signals from each branch (100, 101) with that branch's local oscillator (208, 209) which constitutes a part of the signal equalization. A diversity processor (105) performs bit by bit selection on the re-aligned signals, maximal ratio combining of the re-­aligned signals, or equal gain combining of the re-aligned signals, followed by a sequence estimation which uses similarly selected or combined channel distortion compensation parameters to complete the equalization process on the new signal.

Abstract: In a digital radio telephone transmitter an output pulse with e.g. cos²-shaped edges is produced by a voltage controlled power amplifier (1). When known control loop circuitry is used, the power (Pout) of the output pulse will rise almost step-wise at the beginning of the pulse, which leads to the spreading of the spectrum and to rise time delays of the output pulse with respect to the control pulse (TXC) at different power levels. According to the invention a good cos²-shape of the output pulse (Pout) and its tracking of the control pulse (TXC) almost without delay is achieved so that a squarewave pulse (Vp) is added to the control voltage (V2) of the power amplifier (1), the pulse (Vp) starting and ending substantially at the same time as the control pulse (TXC). In a preferred embodiment the squarewave pulse (Vp) is added to the control voltage (V2) only during that time when the control voltage (V2) is below that value, at which the the control loop begins to operate.
