Description

(54) FREQUENCY-TIME SIGNAL GENERATOR The duration of the frequency dryer is determined by the division factor of frequency divider 8, which determines the pulse propagation period of binary counters JCOB 13 and 13, and the frequency of phase manipulation s of the FM signal F, since the minimum time interval - between which the instantaneous phase difference of the switched - oscillations is zero, is determined by the value of l / f. Y | T the equalizing signal with fluctuating-named moments of transitions of elementary signals is delivered through the inverter // to the key 9 and immediately to 9. To the second inputs of the mentioned keys and drives the gates from the logic circuit 16, with which 15, the initial conditions of the counters J3 and 13 are set temporally. With the help of the trigger 10, a signal is generated, the fronts of which coincide with the moments of the drive of the "hinge differences of the phases of any comrade-90. mykh fluctuations. The antiphase signals of the molar mold form, removed from the trigger 10, are supplied to the keys 12 and 12, with / by means of which the impeller B pushing from divider 8 is connected to the binary 2.5 counters 13 and 13. These counters together with diode arrays 14 and 14 produce. Successively shifted in time pulses, 11 which are used to control the switch 17. Keys 15 and 15 prevent 30 of the control signal from the first diode array that is not working. To obtain the number of frequency steps in the message element, equal to, where m is the number of triggered cells in the counters, and / fe is O, 35 1, 2, 3, ... 2, the input terminals of the element 16 can be connected to the corresponding outputs of diode arrays 14 and 14 (a, b, c, d, and a, b, c, d). The output divider / 8 allows the required frequency separation between the frequency positions. The subject and the h-r e e and 1. A time-frequency signal generator comprising a series-connected frequency synthesizer, a multi-pass switch, an output divider, characterized in that , in order to increase the stability of the time-frequency signal without a phase interruption while simultaneously simulating the number of narcical frequencies, the output. to the second inputs of the control node, 2. The generator of claim 1, characterized in that the control node contains a frequency divider, the output of which is “connected” to the input of two strings, each of which consists of a p-successively connected first key, counters, a diode matrix and a second key, another input of the last one connected to the track input. the first key of the node management 3. The generator PP. 1 and 2, characterized by the fact that the strut assembly consists of -consistently connected the first key and the trigger, to the second input of the latter through a second key, connected to the output of the inverter, to the input of which is connected to the input-one of the first key, and The combined inputs of the mentioned keys are connected to the “OR.
