摘要： Operative monitoring of track brakes involves passing an electric current through a winding of a brake magnet, measuring the electric current and comparing the temporal progression of the measured current with a saved temporal progression of a reference current. Comparison is achieved by calculating the difference between the measured current and the reference current. The difference between measured current and reference current may be temporally integrated and compared with a threshold value. To determine a magnetic coupling between track brake and track, a calculation may be made as to whether the measured current has local minima and/or local maxima during the activation of the track brake, only the temporal progression of the measured current as the current increases being subjected to a comparison with the reference current. The current may be activated in pulses, with the comparison of the measured current and the reference current being restarted with each pulse.

摘要： A stereo multiplex encoder (MPX) for FM transmission with a digital signal processor utilizes residual sideband modulation in stereo transmission instead of the conventional double sideband modulation. The adjustment of the sampling frequency to the modulation frequency (fmod=fs/2) is carried out, so that the antialiasing filter of the DAC can be used which produces the residual sideband modulated signal.

摘要： A method for demodulating pulse messages, which have been converted into modulated signals, preferably for wireless digitized speech transmission, which is distinguished by minimal technical outlay and which can be carried out using circuits which can be designed in integrated circuit technology. The signal which is to be demodulated is subjected to quadrature modulation. Of the two quadrature components which have been thereby obtained one is subjected to a differentiation or an integration and the signal obtained in this manner and the signal of the other quadrature component are supplied, after analog-to-digital conversion, to in each case one comparator (9, 10). The digital output signals of the two comparators (9, 10) are assembled by means of a coincidence gate (11) to form the pulse message.
