Abstract

The invention relates to a waveform signal and a circuit, and particularly relates to a system and a circuit with heart sound-like waveform signals. Real heart sound signals of human are basic materials for the study of heart sound of human. However, real heart sound signals are difficult to acquire. Thus, it is very necessary to design a simple system to simulate the heart sound signals of human in medical research. At present, there are few systems with heart sound-like waveform signals and circuits for implementing the same. In order to overcome the shortcomings of the prior art, the invention provides a waveform signal system with only five items, and the output signals of the system have the same waveform as the heart sound signals of human. The invention designs a circuit for implementing the system. The circuit with heart sound-like waveform signals designed by the invention is composed of three channels of inverting adders, inverting integrators, inverters and multipliers composed of integrated operational amplifiers (LF347N), resistors and capacitors. A very good signal source is provided for aspects such as research of human heart sound signal control.
