摘要：
In the digital meter for measurement of mechanical properties of human vascular system to the converter of mechanical vibrations the first and second current amplifiers are additionally introduced, those are connected in series to each other and to the first current amplifier, noise-suppress amplifier-converter "voltage-current-voltage" and the second voltage comparator, the outputs "d1" and "d2" of the first and second voltage comparators are connected to inputs "d1" and "d2" of the port P4 of the microcontroller. The inputs "a1" and "b" of the noise-suppress amplifier-converter "voltage-current-voltage" and the matching amplifier are connected, respectively, with analog inputs "a1" and "b" of the port P0 of microcontroller which are inputs channel switch unit built into it and connected to the input of the built-in analog-to-digital converter. The input of the first current amplifier is connected to the first terminal of the transformer secondary inductance coil, the second terminal of which is connected to the ground bus. The input of the matching amplifier is connected to the interconnected outputs code-controlled sinusoidal signal generator and the second and fourth terminals of the transformer primary inductance coils. At that the analog output DA1 of the microcontroller, which is the output of the first built-in digital-to-analog converter, through the input "i1" of the second current amplifier is connected to the input of the membrane initial position stabilization unit the output of which is mechanically connected to the membrane which is connected through a duct with a stethoscope affected by mechanical pulse vibrations of the blood vessel walls of the vascular system of the person.В цифровом измерители механических свойств сосудистой системы человека в преобразователь механических колебаний дополнительно введены первый и второй усилители тока, последовательно соединенные между собой и с первым усилителем тока, шумоподавляющий усилитель-преобразователь "на
