IPC: H03K3/02
Abstract: 1,054,652. Multistable devices; transistor circuits. INSTITUT MATEMATIKI SOAN USSR. Jan. 10, 1964, No. 1182/64. Headings H3A and H3T. A multistable device in which the different stable states are represented by different output frequencies and values of D.C. control voltage comprises a voltage source having line spectrum of different frequency signals, a voltage tuned circuit and a detector, filter and amplifier for converting the output of the tuned, circuit to an amplified D.C. signal for application to the control input of the tuned circuit. The line spectrum source is connected via capacitor 20 to a tuned circuit comprising coil 21, capacitor 22 and voltage variable capacitor 23 and the tuned circuit output is connected to an amplifier detector including transistors 25, 26 which supplies a D.C. signal to the junction of capacitor 22 and the variable capacitor 23. The arrangement is such that the circuit is stable when one of the spectrum components w 1  . . . w n , Fig. 3, occupies a position on the left-hand slope of the tuned circuit response curve, i.e. position B, the position on the curve and hence the amplitude of the derived D.C. control voltage varying with different spectrum components. If the circuit is tuned such that a component falls on the opposite slope, i.e. position A, positive feedback of the D.C. signal to the control input acts to move the response curve to position B. The circuit may be shifted from one stable state to another by interrupting the D.C. feedback path for a period sufficient to allow the D.C. control signal to discharge to a level which tunes the circuit away from the influence of the spectrum component to which it was tuned, discharge then continues until the circuit is aligned with the next spectrum component. In a second method the spectrum component input is removed and replaced momentarily by an auxiliary spectrum component signal having components positioned between the components of the original signal, the circuit then tunes first to the adjacent auxiliary component and when this is removed and replaced by the original spectrum to the adjacent component of the normal spectrum. Fig. 6 (not shown), indicates an arrangement in which the tuned circuit frequency is fixed and the spectrum components are mixed with the output of a local oscillator controlled by the D.C. control signal and Figs. 9 and 11 indicate arrangements in which an amplifier is not provided and the feedback is internal.
