    摘要: A circuit arrangement and a method for obtaining a signal for use in downconverting a signal of a relatively high frequency VCO (7). A pulse train (S 1 ) is generated as a function of a reference signal which is then fed into an oscillator (2) so as to generate a signal (S 2 ) modulated by said pulse train (S 1 ). The resulting signal is fed into a band pass filter (4) which in turn outputs a selected frequency band (S 3 ) to be mixed with the signal of VCO (7) in order to obtain the down converted control signal for phase locking.

Es ist dazu ein Schwingquarz (1) mit mindestens zwei unterschiedlichen Resonanzfrequenzen vorgesehen. Ein Emitter eines ersten Transistors (2) ist über den Schwingquarz mit einem Emitter eines zweiten Transistors (9) verbunden. Die Basen der Transistoren sind jeweils über Basisschwingkreise (11,17) mit einem unteren Bezugspotential und die Kollektoren der Transistoren jeweils über Kollektorschwingkreise (5,14) mit einem oberen Bezugspotential verbunden. Die Basis jeweils eines der Transistoren ist elektrisch mit dem Kollektor jeweils des anderen Transistors verbunden. Die Basen der Transistoren sind jeweils über Wechselstromkoppler an das untere Bezugspotential angeschlossen.

    摘要: A frequency generator produces two widely spaced frequency outputs at the terminals of a single transistor. There is also disclosed a fixed frequency dual downconversion receiver, comprising: an analog first downconversion and IF filter stage; means for one-bit coding of the downconverted signal; and means for second downconversion by digital subsampling. The receiver is particularly suitable for use in GPS appliocations, and the frequency generator can advantageously be used to produce the local oscillator signal for the first mixer, and a clock signal for the digital subsampler.

Durch Zusammenschalten mehrerer Generatoren mit unterschiedlichen, einstellbaren Grundfrequenzen und eine Einstellbarkeit von Koppelgliedern können beliebige Frequenzgänge und Schwebungen erzeugt werden, die sich als besonders wirksam erwiesen haben. Vor allem wird die für den menschlichen Körper gefährliche Komponente der Netzfrequenzen von 50-60 Hz vermieden.
