Abstract

The invention relates to medicine, the treatment of interference currents. The purpose of the invention is to increase the low frequency stability. To do this, use a device containing an oscillator 1, two circuits containing digital dividers 2, drivers 3,4, amplifiers 5, electrodes 6, an additional divider 7 connected using switching device 10, reducing the split frequency by 1 Hz and switching the register of the counter 9 so that the interference frequency rises. The device is turned off with the switch 8. The variable frequency division is obtained by blocking individual or several additional pulses of the following pulses, due to connection to the counter generator. You can get the difference in frequencies of 1.2, 4.6 Hz, etc. The generator generates frequency 11 supplied to a divider with a constant division factor and to a divider operating according to a program, from the output of which a pulse 12 is received. to electrodes. The interference frequency does not depend on either the temperature difference or the X-voltage fluctuations. 1 il. WITH

Broker medicine relates to medicine, in particular, treatment of interfering HHOHFibiMH currents.

The core of the invention is to improve the stability of the low frequency

The drawing shows a block diagram of the device.

 The device contains a generator 1, two circuits, each of which contains digital dividers 2, drivers 3 and 4, amplifier 5 and electrodes 6, an additional divider 7, switch 8, counter 9, switching device 10,

The device works as follows.

The high output frequency of the generator 1 is divided into frequencies of various sizes.

Variable frequency division is obtained by blocking individual or several subsets of the following pulses. The change in frequency division can be accomplished by connecting to a counter generator. With a generator frequency of 50 MHz with 10,000 times division of the frequency and with a divided frequency of 5,000 Hz, the smallest difference of frequencies is 0.5 Hz, the difference in frequencies in I, etc.

You can semi1, 2 4 and 6 Hz

I Generator 1 generates a frequency 115 which is fed to a divider with an I constant division factor and to a divider operating according to a program from the output of which a pulse 12 is received. In the former, this pulse is converted into a symmetric right Q signal 13. Shaper 3 converts 13 into a sinusoidal current 14. The shaper 3 consists of a frequency filter. Amplifier 5 fails

current to the electrodes. An additional divider 7 J which is connected using the switch of device 10 reduces the split frequency by 1 Hz and switches the register of counter 9 so that the interference frequency increases. The device is turned off using the switch 8.

If the division factor and the frequency of the generator recorded the difference in frequency, the interference frequency does not depend on either the temperature difference or the voltage fluctuations.
