“…The signal generator did not offer the necessary precision at low amplitude ranges, suffered from voltage offsets and was not tested for temperature stability. It required an enhanced user interface for the system, increased bit resolution of the resulting ECG signal and also significant improvement in the accuracy of the output signal at the lower end of the output amplitude range by using an original approach to the digital-to-analogue conversion (DAC) stage of the generator which suffered from similar limitations to those outlined by Chang Chien [2]. The hardware platform greatly increases its usefulness beyond purely software based ECG simulators [6].…”

The use of ECG recordings as a diagnostic tool relies heavily on the fidelity of the recorded signal. ECG signal synthesis is therefore vital in the testing and commissioning of ECG recording equipment. A number of signal generators have been previously presented in the literature, however the platforms they were developed on have become dated and more importantly their architectures do not provide a temperature-stable generator capable of operating at the necessary levels of precision in the voltage range required. The shortcomings of previous instruments are overcome here using a novel approach to the digital and analogue stages of the signal conditioning process. It offers significantly increased precision over the 100 μV-10 mV amplitude range, includes voltage offset correction and full temperature stability. The devices capability has been analysed and tested significantly more than any of its predecessors, and the results demonstrate it is a significant step forward in ECG signal synthesis.

The aim of this work is to design and implement an ECG generator for didactic biomedical engineering laboratory. The proposed generator provides analog ECG signals using synthesized or experimental records. The technique used in this work consists to generate the desired ECG waveforms through the PWM outputs of an Arduino board and low-pass filter. To provide many educational functions in both analog instrumentation and digital processing, the generator supplies output voltages in asymmetric or differential mode. To allow the user to setup the ECG signal to be generated, a LabVIEW application has been implemented. Experimentations on proposed generator and results were accomplished using the NI USB 6009 acquisition module and NI MAX software.

Biomedical applications are one of the important research areas of recent years. One of these fields of study is biomedical signals. In this study, the Normal Sinus Rhythm and three arrhythmic ECG signals (Ventricular Tachycardia, Ventricular Paced and Atrial Flutter), one of the vital sign signals, were designed and implemented to work on FPGA chips using the Xilinx-Vivado program with VHDL. Matlab-based ECG signals were taken as a reference and compared with the results obtained from the FPGA-based ECG signals design. Then, the structure used in the design and the test results obtained from the study have been presented. The designed ECG signals were synthesized for the Zynq-7000 XC7Z020 FPGA and observed from the oscilloscope using the 14channel AN9767 DA module. FPGA chip resource consumption values obtained after the Place-Route process are presented. According to the results, the maximum operating frequency of Normal Sinus Rhythm and Ventricular tachycardia signals on the FPGA was 657.614 MHz and the maximum operating frequency of the Ventricular Paced and Atrial Flutter signals on the FPGA was 651.827 MHz. The maximum MSE value obtained from FPGA-based ECG signal design is 1.2319E-02.In this study, it has been shown that the FPGA-based ECG signal generation system, which is implemented as hardware, can be designed using FPGA chips and can be safely used in biomedical calibration applications. Other arrhythmic ECG signals can be designed and implemented using similar methods in future studies.
