    摘要： Automatic waveform analyzing apparatus for deriving arbitrary waveforms by the synthesis of a plurality of optimumly weighted fundamental waveforms whose optimum weighting factors are determined by repeatedly sampling said plurality of fundamental waveforms at a plurality of sampling points and modifying previously established values for such weighting factors in response to values obtained at each sampling point is provided in accordance with the teachings of the present invention. In the automatic waveform analyzing apparatus according to the present invention, a plurality of analog memory elements are disposed in accordance with the sampling points selected such that one such analog memory elements is associated with each sampling point. The analog memory elements are read and each readout pulse derived therefrom is branched and apportioned into a plurality of output signals representing the value of each fundamental waveform as evaluated at the sampling point associated with the analog storage element producing such readout pulse. The branched and apportioned output signals from all of the analog memory elements are then selectively added on the basis of the correspondence of the associated fundamental waveforms associated therewith and a summation signal is produced for each fundamental waveform relied upon. Each summation signal produced is then apportioned on the basis of the value of the fundamental waveform associated therewith at each of the sampling points selected. Such apportioned values are then selectively added and compared to corresponding values of the arbitrary waveform. The analog storage element associated with the sampling point at which the selective addition and comparison has taken place has its contents selectively modified. This operation is repeatedly performed at each sampling point until the selective comparison indicates that an equivalent waveform has been synthesized.

    摘要： A rectifier is connected to transfluxor output winding. A first feedback circuit is connected between rectifier output and setting winding, a second feedback circuit between rectifier output and blocking winding. The first and second feedback circuits have first and second three-stage amplifier respectively. The operating voltage for one stage of first or second three-stage amplifier applied selectively to produce increase or decrease of stored analog value respectively.

    摘要： A magnetic core memory wherein states of partial magnetization as well as magnetic saturation are employed. In the course of reading information from a core the core is first switched to one extreme state of magnetization to obtain a data readout pulse and subsequently the core is switched to the opposite state of magnetization to obtain a reference data pulse. The ratio of the magnitudes of the reference pulse and the data pulse is measured and is employed to define the state in which the core resided prior to interrogation. Cores are placed in a stable state either a state of partial magnetization or a state of full magnetization, by switching the core from one extreme state of magnetization to the other extreme state of magnetization to obtain a data reference pulse and subsequently the magnitude of this reference pulse is compared with the magnitude of the data pulse which is generated by the writing of new information into the core. The core drive which is employed for writing is terminated when the ratio between the latter data pulse and the reference data pulse has reached a desired ratio.
