The invention relates to automation and computing and can be used in electronic computing systems and discrete automation systems. A summation device is known, which consists of two logical elements, which are made on miniature vacuum microwave devices of the reflective-klistron type with an electronic hysteresis, in: the input device resonators are connected to the output device reflectors and the power line, and through total resistance - the second power bus, the reflectors of the input devices are connected to each other and to the third power bus, all the reflectors are connected by capacitors to the bus voltage of the modulating voltage source, and the output resonators outputs connected to the buses and transfer amount Li 3. This device is characterized by insufficient speed and the restriction of the functionality of. The closest to the proposed is a multiplying-summing device, containing a series-connected pulse generator and three generators with exponential linear sections in the characteristic of the transition process, executed in the form of microwave devices with an electronic hysteresis loop and connected through a comparison element and keys to a pulse-to-continuous converter J2 A disadvantage of the known device is relative complexity. The purpose of the invention is to simplify the device. The goal is achieved by the fact that in the multiplying-summing device containing the first, second and third generators with exponential and linear sections, the characteristics of the transient process are made respectively as the first second and third microwave devices with an electron hysteresis loop, the reflector and cathodes of which are connected respectively negative and positive supply voltage buses and a source of the blocking signal, the first inputs of the resonators of the first and second microwave devices with electronic loop The hysteresis is the input of the device, respectively; the first output of the first resonator and the output of the second microwave device with an electronic hysteresis loop are connected respectively to the second input of the second resonator and to the input of the third microwave device resonator with an electronic hysteresis loop, the third output of the third microwave device with a loop The electronic hysteresis is the output of the device, the second outputs of the resonators of the first and third microwave devices with an electronic hysteresis loop are connected to the source irai signal. Fig. 1 is a schematic diagram of the proposed device in Figs. 2 and 3 — the use of temporal characteristics of transient processes for performing arithmetic operations of summation (Fig. 2) and multiplication (Fig. 3) in Fig. 4 - the process of establishing oscillations in a microwave device with electron hysteresis loop. The summation device (multiplications) contains inputs 1 and 2 connected to the inputs of the resonators of the microwave devices 3 and 4 with the electron hysteresis loop, the output of the resonator of the microwave device 5 with the electron hysteresis loop is the output 6 of the device, the reflectors 7, 8 and 9 of the microwave devices 3, 4 and 5 with an electronic hysteresis loop are connected to the bus 10 of the negative power supply voltage; the second outputs 11 and 12 of the resonators of the microwave devices 3 and 5 with the electronic hysteresis loop are connected to the source of the locking microwave signal 13, the cathodes 14, 15 and 16 of the microwave devices 3 , 4 and 5 with e loop Electron hysteresis is connected to the bus 17 of the positive supply voltage. The first codes of the resonators of the microwave devices 3 and 4 are the outputs 18 and 19, the second input. The RF device 4 is the input 20. The device operates as follows. After removing the locking signal B from the microwave device 3 with the electron hysteresis loop - the first summable (multiplier) and the microwave device 5 with the electron hysteresis loop - the sum (product) begins to increase oscillations when the first summable (multiplier) reaches a predetermined value, the reflector voltage 8 On the second microwave device 4 with an electric hysteresis loop, it enters the generation zone (or the electron hys3, Terezis region) and allows the onset of oscillation buildup in the microwave device 4 with an electronic hysteresis loop. When the signal of the microwave device 4 with the electron hysteresis loop reaches beyond this value, the voltage of the reflector 9 on the microwave device 5 with the electron hysteresis loop — the sum (product) leaves the generation zone, the buildup of oscillations in the microwave device 5 with the electron hysteresis loop stops. The summation is carried out in accordance with the ratio,, where t, t., T are the time intervals that are directly proportional to the first term and, the second term 1) 2 and the sum U, a, k are constant coefficients equal in the special case to one .
