Title: HF receiver with single IF stage - has nonlinear amplifier tuned to harmonic of IF
Inventor: HANSEN JENS DIPL ING
IPC: H04B1/26
Filed: 1980-09-27
Abstract: The signal entering from the aerial (1) passes through an HF amplifier (2) and is then mixed (3) with the output of an oscillator (4) to give an intermediate frequency via a band pass filter (5). The IF is amplified (6) and applied to a circuit element with a non-linear transfer function (7). The non-linear amplifier (7) enhances the harmonics in the IF signal from which one is isolated by a band pass filter (8) and a highly frequency selective amplifier (9). This selected frequency is then demodulated (10) and, after amplification (11), applied to the loudspeaker (12). The use of only one mixer stage improves the signal to noise ratio w.r.t that of a multi-mixer receiver. The receiver requires no more filter components than a simple superheterodyne.

Title: Circuit arrangement for electronically coupling two incremental transmitters
Inventor: WETZEL MANFRED
IPC: G01D5/244
Filed: 1981-02-20
Abstract: In a circuit arrangement for electronically coupling at least two incremental transmitters which, in dependence on the longitudinal movement of two objects relative to one another or to a fixed point, output pulses, the number of which corresponds to the respective extent of the movement, particularly for adjusting devices on tool measuring machines or the like, the problem is to create an electronic coupling of the incremental transmitters in which a single display of the measurement value plus sign for the total movement of at least two objects which can be moved with respect to one another and with respect to a fixed point is made possible. For this purpose, it is proposed to clock the pulse sequences of the two incremental transmitters alternatively by a clock generator with a frequency which is higher than that of the maximum rate of movement of the objects of corresponding frequency, and to provide an adding device for adding the two pulse sequences, the output pulses of which are supplied to a display device or similar evaluating device. The incremental transmitters output mutually phase-shifted pulse sequences for additive/subtractive coupling. A pulse converter detects the direction of movement on the basis of the phase angle. <IMAGE>
