Abstract
A circuit device for effecting phase and frequency comparison of two signal voltages, at least one of which is divided into two partial voltages, and in which, in case the frequencies of the two voltages of The signal to be matched coincide, a phase-dependent directional voltage is produced, and in which, if the frequencies do not coincide, to produce a directional voltage dependent on the dynconia, the resulting difference voltage difference whose polarization is a function of the The address of the dithering is converted, storing its last respective peak value in such a way that it will have a time function curve in which the value of the voltage type of one polarity is substantially greater than the peak value of the other polarity to the average value, characterized in that each time a voltage derived from the two signal voltages is applied to each base section emitter of two transistors whose section The emitter collector collectors are connected in series with a supply voltage generator, and whereby the polarization potential of each emitter base section, produced, e.g. by a battery or a circuit R.C. whose time constant is greater than the period duration of the minimum frequency difference that can be expected, is less than the peak value of the applied sum voltage, but higher than the type values of the respective individual voltages of this sum voltage, and because, if the frequencies of the two voltages being compared do not coincide, the potential that appears at the connection point of the two series transistors, of the last respective peak value of the difference voltage voltage applied to this connection point, it is stored by means of a storage device of known type per se (eg a capacitor, bistable multivibrator, etc.) from which the directional voltage dependent on the frequency is obtained.
