摘要： A resonator circuit formed in MOS technology for scanned analog signals, wherein such circuits are constructed for use with accumulators and information processing is accomplished by means of switched capacitors which are charged or respectively connected to each other by way of clock pulse transistors. In the present invention, the realization of general ladder networks or branching circuits for builders in single layer MOS techniques is accomplished by utilizing a second continuous branch which is switched to a first accumulator stage by clock pulse switches and is connected with a reference potential through a capacitor as well as to a further accumulator input through a series switch. The signal series arms are connected with the outputs of the total accumulator arrangement by way of time delay transit elements. The total accumulator arrangement is expanded to a resonator of the type of a four pole network having two inputs to which one respective transmission and one respective reflection output is assigned by utilizing difference elements and transfer elements. The arrangement of the invention is suitable for use as general branching filter circuits, and an increase of the dynamic range by better suppression of the clock pulse pickup and the harmonic distortion of the second order occurs by utilizing push-pull arrangements.

摘要： A switching circuit (2) consisting of CTD lines (p.sub.1,q.sub.1,p.sub.2,q.sub.2,p.sub.3,q.sub.3) is specified in which the properties characteristic for non-unidirectional microwave lines (FIG. 1) are also retained for CTD switching circuits (FIG. 2). To that end, CTD lines (for example, p.sub.1,q.sub.1) exhibiting mutually opposing conducting directions are combined into a line pair and each incoming line (p.sub.1) is connected with each out-going line (q.sub.1). The connection ensues partially via CTD lines (c.sub.1 +c.sub.1 ') and, for the other part, via a galvanic line (L.sub.1). Such switching circuits can be employed for the construction of CTD filters with steepness-increased transmission characteristic and also for the construction of correcting circuits.

摘要： A filter comprising a cascade arrangement of closed line CTD filtering loops has an intermediate CTD coupling loop formed with the adjoining output coupling of the preceding filter loop and input coupling of the succeeding filter loop. Disturbing self-oscillations outside the desired passband are eliminated by adjusting the voltage amplification factors of the amplifiers within the intermediate coupling loop, for example to from about five percent to about fifteen percent less than values selected to give a pure reactance branching circuit at the middle pass frequency. The resulting slight distortion of the transmission characteristic in the pass band of the filter can then be compensated by adjusting the amplifications of other amplifiers, and if necessary the capacitance conditions can be additionally altered.

摘要： A combiner circuit employs the maximum power method, in which the phase of one of the signals is varied such that the power of the aggregate signal (main and diversity) is varied such that the power of the aggregate subsequently formed is optimally high. In order to improve this combining method that becomes less and less efficient with increasing bandwidth and number of steps of signals, particularly given selective fading, it is provided that the combiner circuit contains a control circuit for the combination phase, the control circuit being composed of a maximum power control circuit and of two preceding, supplementary circuits for varying the amplitudes of the main and diversity signals. The amplitude variation of the main and diversity channel spectrum occurs in such a fashion that the signal spectra are split in the appertaining branches of the two supplementary circuits by respective identical bandpass filters for the lower spectrum half and the upper spectrum half, the powers of the sub-bands are measured at the outputs of the bandpass filters and both sub-bands are set to approximately identical values.
