Consider the operation of the device.

For easy operation, setup and fallen the least significant digit U. Generator 5 produces sinusoidal oscillations of fixed frequency, peak value which is equal to the width of the operating range of the input voltage of the ADC 2. Using the FSB 7 is achieved by the shift of these fluctuations on the angle =-90o.

To the second input 16 of the device applied DC voltage z equal to the value of the modulus of the vector information to the ADC input 2 from the first input 1 of the device applied DC voltage x equal to the value of known orthogonal component of the vector. Code on the digital output of the ADC 2 is equal to

< / BR>
Code2is fed to the digital input of the first DAC 3, to the input of the reference voltage which is applied sinusoidal voltage output from the GOS 5. As a result, the output of the first DAC 3 is a sinusoidal voltage, the effective value of which is equal to

< / BR>
The voltage applied to the first input of the adder 4.

Chain jobs voltage proportional to the designated component of the vector, consists of items 5, 7, 9, 23 devices. We will begin consideration of the operation of the device at any point in time at which the contents of the counter 23 is zero. In this case, the output voltage of the DAC 9, imitating second opustitsa (see Fig.3)

< / BR>
Converter PNP 10 is converted from the information input AC voltage to DC equal to the amplitude value of the input voltage, i.e., z Is the voltage stored in the UPS 12.

The control units 10 and 12 of the device is performed as follows. At the beginning of each period of the sine wave output GOS 5 on the leading edge of the output voltage BUT 6 starts the one-shot 11. Output a short pulse of the past, influencing the control input of switch 29 PNP 10 (see Fig. 2), discharges the capacitor 28 to zero voltage. Then is the charge of the capacitor 28 to the amplitude value input sinuosity. The subsequent discharge of the capacitor 28 is prevented by the diode 27. By reducing the sine wave to zero (this happens in the middle of the period) BUT 6 releases, triggering the one-shot 13, output a short pulse which enters the output voltage PNP 10 in the UPS 12.

After passing 3/4 the length of the period of the sinusoid output voltage GOS 5 releases BUT 8, powering the one-shot 19, output a short pulse which is applied to the second inputs of elements AND NOT 17 and 18.

Given that pamumuhay due under dead zone) from the output of the FM 21 applied voltage /z-x/>U, its output is a single voltage applied to the third inputs of elements AND NOT 17 and 18.

Because at this point in time to invetnory the input of the comparator 15 with the output of the UPS 12 applied voltage equal to <z, to direct the output of the comparator 15 is a single voltage, and on and inverse - zero. Therefore, the pulse output of one-shot 19, passing through the element AND-NOT 17, enters the progressive input of the counter 23 and increases its content per unit - it becomes equal to 0001 (if 4-bit version). Code counter 23 is applied to the digital input of the DAC 9, the output is a sinusoidal voltage, the effective value of which is equal to (see Fig.3)

< / BR>
Given that the stress applied from the output of the FSB 7 to the input reference voltage of the second DAC 9, lagging the voltage GOS 5 90othe voltage lagging the voltage by 90o(see Fig.3).

The output voltage of the adder 4 with this time is:

< / BR>
The module of the resultant vector is equal to (see Fig.3)

< / BR>
Using PNP 10 AC voltage is converted to DC voltage:

< / BR>
Given that U'12=U'10<z, to direct the output compai 5 again increases the contents of the counter 23, its output code is set to 0010, and the DAC output voltage 9 takes the value:

< / BR>
Accordingly, the output voltage PNP 10 and the UPS 12 becomes equal

< / BR>
Finally, in the third period of the sine wave output GOS 5 the contents of the counter 23 becomes equal to 0011, and the DAC output voltage 9 reaches the value:

< / BR>
Output voltage PNP 10 and the UPS 12 reaches the value:

< / BR>
In the alignment of the input voltages of the comparator 15 releases, the voltage of the direct output drops to zero, closing element AND-NOT 17 and opening the item AND NOT 18. Also drops to zero the output voltage of the comparator 20, covering both element AND-NOT 17 and 18 for the passage of pulses from the output of one-shot 19. Further, the content of the counter 23 is not changed, and the output of the DAC 24 from this point on there is constant DC voltage:

< / BR>
Such a balanced rest mode continues until you change the values of the module of the vector z or known orthogonal component of the vector x. If the result of such changes module unknown orthogonal component of the vector y would be increased (by a vector diagram in Fig.3), the contents of the counter 23 is incremented for rogressivnye input of the counter 23, if the module we would have to decrease, then the contents of the counter 23 is reduced due to the receipt of pulses from the output of one-shot 19 through the element AND IS NOT 18 regression input of the counter 23.
