摘要： Radio receivers which scan through a predetermined band of the radio spectrum, in a station-seeking mode, must independently detect whether the currently tuned frequency is the central frequency of the transmitting station and whether this transmitter provides a signal whose strength is sufficient, i.e. whose strength exceeds a predetermined threshold value. Once these two conditions are satisfied, the radio generates a "stop" signal which terminates the station-seeking mode, i.e. keeps the tuning circuit set to the frequency which provided the sufficiently strong signal. The present invention provides an unusually simple way to determine whether these two conditions are satisfied, by using a Finite-Impulse-Response digital filter (2) to extract a d.c. component of the demodulated signal (MPX), for comparison (6) with a predetermined maximum value, and by filtering (10) a field strength signal (FST), for comparison (11) with a predetermined minimum value. When both conditions are satisfied, a simple AND-gate (8) generates the stop-signal.

摘要： Digital tuning of a locally generated frequency supplied to a frequency converting mixer, a mobile radio receiver is provided with great economy of components by utilizing the sampling rate oscillator for an analog-to-digital converter provided at the output of an analog intermediate frequency amplifier of the receiver as the source of the difference frequency for a phase locked loop (PLL) for control of the phase of a local oscillator for the mixer or mixers. All frequencies used to supply local oscillations to mixers, as well as the operating frequency of the phase locked loop are integer number multiples of the sampling rate pulse generator. Some division stages have fixed dividers and others have divisors selectable by a tuning processor and in some of the divisor connections it is useful to interpose a fixed or selectable-factor multiplier. A sampling rate of 42.75 MHz is recommended and an intermediate frequency amplifier frequency which is a rational number multiple of 57 kHZ, preferably 10.6875 MHz are similarly recommended.

摘要： In a demodulator for use in the Radio Data System (RDS) as defined by the European Broadcasting Union, transmission of these signals is carried out through phase shift modulation of a suppressed subcarrier, a multiplex signal, which contains a signal with the frequency of the subcarrier passes through a band-pass filter and an amplitude limiter, and the amplitude-limited signal, having a carrier frequency, is sampled at a sampling frequency that is a multiple of the frequency of the subcarrier. The sampling values are summed over a preset portion of one period of the subcarrier. The summed sampling values are supplied to a digital signal processing circuit.

摘要： The Radio Data System (RDS) protocol promulgated by the European Broadcasting Union provides for alternate frequencies (AF) for the same broadcast. Receivers periodically switch over to such an alternate frequency, leading to momentary crackling noises. In a radio receiver having a device for temporary switchover from a received frequency to some other frequency, substitute signals are inserted into the audio signals that are interrupted during the temporary switchover. The substitute signals are formed from the audio signals before and optionally also after the temporary switchover.

摘要： To prevent theft of a car radio (R), the radio unit itself is located in the vehicle (V) in a suitable secure location. The radio is controlled by a two-part control unit, in which one part of the control unit forms a connection part (1), secured to the vehicle, for example, by a goose-neck (5) or the like, and the other part forming a control part (21) which is separable from the connection part. Interengaging dovetail track-and-groove connections permit ready removal of the control part (21) from the connection part, so that a user may remove the control part, and thus not leave any indication in the vehicle that it contains a car radio. The control part contains the necessary control buttons and display functions to operate and control the car radio, the connection part merely including a plurality of contact terminals which, with the control part removed, are depressed below a top surface of a housing (2, 3) of the connection part.

摘要： The primary winding of a high-voltage transformer is periodically connected to an operating voltage source at the television line scanning frequency. The secondary winding is subdivided into several component windings which are connected to each other through diodes. A further diode provides the output for the high voltage. A somewhat similar circuit with interposed diodes can provide a center tap and full-wave rectification. A control voltage derived by voltage division from the high voltage is supplied to regulating means for holding the high voltage constant by controlling the width of the driving pulses for the semiconductor switch or by directly controlling the operating voltage connected to the transformer through the semiconductor switch.

摘要： A T-network with a capacitor in the shunt branch and similarly poled diodes in the series branches provides an electronic switch for the IF signals in a VHF receiver exhibiting 58 dB of attenuation in the block condition and negligible attenuation when the diodes are conducting. The resistance across the input of the IF amplifier and, if necessary, a resistance in the switching voltage path, determine the amount of current through the diodes when they are conducting under application of the switching voltage. Low pass filtering in the switching voltage leads and blocking capacitors in the signal connections of the switch restrict signal and switching voltages to their respective paths. Applying a positive potential to one switching terminal closes the switch and applying it to the other switching terminal opens it.

摘要： To permit transmission of traffic information by amplitude modulation in the medium wave band without disturbing audio signals being broadcast, a stereo pilot tone of frequency f.sub.pt below audible range is generated, as well as first and second sinusoidal signals of f.sub.1 =m.sub.1 /n.multidot.f.sub.pt and f.sub.2 =m.sub.2 /n.multidot.f.sub.pt, in which m.sub.1, m.sub.2, and n are different integers. The carrier is modulated by the stereo pilot tone and the first and second sinusoidal signals in such a manner that the phases thereof are different and further, when added, they do not essentially exceed the amplitude of the stereo pilot tone.
