Anti-interference pulse signal conditioner

Abstract

The invention discloses an anti-interference pulse signal conditioner. The anti-interference pulse signal conditioner comprises a first capacitor, a second capacitor, a third capacitor, a fourth capacitor, a first resistor, a second resistor, a third resistor, a fourth resistor, a fifth resistor, a diode, a first power source, a second power source and an amplifier. The anti-interference pulse signal conditioner can filter and amplify input signals, remove direct current and extremely-low frequency interference signals, restrain high frequency interference, amplify useful pulse signals, and eliminate bias voltage, is simple in circuit structure and is suitable for being used for pulse testing instruments.

Description

technical field

[0001] The invention relates to a signal conditioner, in particular to an anti-interference pulse signal conditioner. Background technique

[0002] In the diagnosis of traditional Chinese medicine in my country, through pulse diagnosis, doctors can have a general understanding of the patient's physical condition, and then prescribe the right medicine. The pulse signal can directly reflect part of the condition of the patient's heart. We can understand the ups and downs of qi and blood in the patient's viscera. With the development of science and technology, there are more and more pulse signal instruments. Nowadays, pulse signal conditioners generally have complex structures and poor anti-interference performance, which restricts the development of pulse signal instruments. Contents of the invention

[0003] The object of the present invention is to provide an anti-interference pulse signal conditioner in order to solve the above problems.

[0004] The pres...
